ice: reduce initial wait for control queue messages
The ice_sq_send_cmd() function is used to send messages to the control queues used to communicate with firmware, virtual functions, and even some hardware.
When sending a control queue message, the driver is designed to synchronously wait for a response from the queue. Currently it waits between checks for 100 to 150 microseconds.
Commit f86d6f9c49f6 ("ice: sleep, don't busy-wait, for ICE_CTL_Q_SQ_CMD_TIMEOUT") did recently change the behavior from an unnecessary delay into a sleep which is a significant improvement over the old behavior of polling using udelay.
Because of the nature of PCIe transactions, the hardware won't be informed about a new message until the write to the tail register posts. This is only guaranteed to occur at the next register read. In ice_sq_send_cmd(), this happens at the ice_sq_done() call. Because of this, the driver essentially forces a minimum of one full wait time regardless of how fast the response is.
For the hardware-based sideband queue, this is especially slow. It is expected that the hardware will respond within 2 or 3 microseconds, an order of magnitude faster than the 100-150 microsecond sleep.
Allow such fast completions to occur without delay by introducing a small 5 microsecond delay first before entering the sleeping timeout loop. Ensure the tail write has been posted by using ice_flush(hw) first.
While at it, lets also remove the ICE_CTL_Q_SQ_CMD_USEC macro as it obscures the sleep time in the inner loop. It was likely introduced to avoid "magic numbers", but in practice sleep and delay values are easier to read and understand when using actual numbers instead of a named constant.
This change should allow the fast hardware based control queue messages to complete quickly without delay, while slower firmware queue response times will sleep while waiting for the response.

ice: sleep, don't busy-wait, for ICE_CTL_Q_SQ_CMD_TIMEOUT
The driver polls for ice_sq_done() with a 100 µs period for up to 1 s and it uses udelay to do that.
Let's use usleep_range instead. We know sleeping is allowed here, because we're holding a mutex (cq->sq_lock). To preserve the total max waiting time, measure the timeout in jiffies.
ICE_CTL_Q_SQ_CMD_TIMEOUT is used also in ice_release_res(), but there the polling period is 1 ms (i.e. 10 times longer). Since the timeout was expressed in terms of the number of loops, the total timeout in this function is 10 s. I do not know if this is intentional. This patch keeps it.
The patch lowers the CPU usage of the ice-gnss-<dev_name> kernel thread on my system from ~8 % to less than 1 %.
I received a report of high CPU usage with ptp4l where the busy-waiting in ice_sq_send_cmd dominated the profile. This patch has been tested in that usecase too and it made a huge improvement there.

ice: add support for sideband messages
In order to support certain device features, including enabling the PTP hardware clock, the ice driver needs to control some registers on the device PHY.
These registers are accessed by sending sideband messages. For some hardware, these messages must be sent over the device admin queue, while other hardware has a dedicated control queue for the sideband messages.
Add the neighbor device message structure for sending a message to the neighboring device. Where supported, initialize the sideband control queue and handle cleanup.
Add a wrapper function for sending sideband control queue messages that read or write a neighboring device register.
Because some devices send sideband messages over the AdminQ, also increase the length of the admin queue to allow more messages to be queued up. This is important because the sideband messages add additional pressure on the AQ usage.
This support will be used in following patches to enable support for CONFIG_1588_PTP_CLOCK.

ice: remove unused struct member
The only time you can ever have a rq_last_status is if a firmware event was somehow reporting a status on the receive queue, which are generally firmware initiated events or mailbox messages from a VF. Mostly this struct member was unused.
Fix this problem by still printing the value of the field in a debug print, but don't store the value forever in a struct, potentially creating opportunities for callers to use the wrong struct member.

ice: Initialize PF and setup miscellaneous interrupt
This patch continues the initialization flow as follows:
1) Allocate and initialize necessary fields (like vsi, num_alloc_vsi, irq_tracker, etc) in the ice_pf instance.
2) Setup the miscellaneous interrupt handler. This also known as the "other interrupt causes" (OIC) handler and is used to handle non hotpath interrupts (like control queue events, link events, exceptions, etc.
3) Implement a background task to process admin queue receive (ARQ) events received by the driver.

ice: Start hardware initialization
This patch implements multiple pieces of the initialization flow as follows:
1) A reset is issued to ensure a clean device state, followed by initialization of admin queue interface.
2) Once the admin queue interface is up, clear the PF config and transition the device to non-PXE mode.
3) Get the NVM configuration stored in the device's non-volatile memory (NVM) using ice_init_nvm.

ice: Add support for control queues
A control queue is a hardware interface which is used by the driver to interact with other subsystems (like firmware, PHY, etc.). It is implemented as a producer-consumer ring. More specifically, an "admin queue" is a type of control queue used to interact with the firmware.
This patch introduces data structures and functions to initialize and teardown control/admin queues. Once the admin queue is initialized, the driver uses it to get the firmware version.
