qed: Fix scheduling in a tasklet while getting stats

Fix this by making caller to provide the context whether it could be in atomic context flow or not when getting stats from QED driver. QED driver based on the context provided decide to schedule out or not when acquiring the PTT BAR window.
We faced the BUG_ON() while getting vport stats, but according to the code same issue could happen for fcoe and iscsi statistics as well, so fixing them too.

net: qed: correct qed_hw_err_notify() prototype
Change the prototype of qed_hw_err_notify() with the following: * constify "fmt" argument according to printk() declarations; * anontate it with __cold attribute to move the function out of the line; * annotate it with __printf() attribute;
This eliminates W=1+ warning:
drivers/net/ethernet/qlogic/qed/qed_hw.c: In function ‘qed_hw_err_notify’: drivers/net/ethernet/qlogic/qed/qed_hw.c:851:3: warning: function ‘qed_hw_err_notify’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format] len = vsnprintf(buf, QED_HW_ERR_MAX_STR_SIZE, fmt, vl); ^~~
as well as saves some code size:

__printf() will also be helpful with catching bad format strings and arguments.

qed: Use dmae to write to widebus registers in fw_funcs
There are several wide-bus registers written to by the fw_funcs that require using the dmae for atomicity. Therefore using the dmae channel functionality was added to the fw_funcs file, since the code is very similar to the previously used code, the structures used were moved to qed_hsi. Due to FW conventions, the names of the flags in the struct changed. Since this required slight modification in the places that set the flags the code was modified to use GET/SET FIELD macros.

qed: Modify api for performing a dmae to another PF
This patch modifies the dmae API to enable performing a dmae operation to another PF. This enables sharing between the llh entries between PFs and thus increasing the amount of filters per PF under certain configurations. The llh entries require using the dmae since the memory is widebus, which requires atomicity in access.

Advance the qed* drivers to use firmware 8.33.1.0: Modify core driver (qed) to utilize the new FW and initialize the device with it. This is the lion's share of the patch, and includes changes to FW interface files, device initialization flows, FW interaction flows, and debug collection flows. Modify Ethernet driver (qede) to make use of new FW in fastpath. Modify RoCE/iWARP driver (qedr) to make use of new FW in fastpath. Modify FCoE driver (qedf) to make use of new FW in fastpath. Modify iSCSI driver (qedi) to make use of new FW in fastpath.

qed: Initialize hardware for new protocols
RoCE and iSCSI would require some added/changed hw configuration in order to properly run; The biggest single change being the requirement of allocating and mapping host memory for several HW blocks that aren't being used by qede [SRC, QM, TM, etc.].
In addition, whereas qede is only using context memory for HW blocks, the new protocol would also require task memories to be added.

qed: Utilize FW 8.10.3.0
The New QED firmware contains several fixes, including: - Wrong classification of packets in 4-port devices. - Anti-spoof interoperability with encapsulated packets. - Tx-switching of encapsulated packets. It also slightly improves Tx performance of the device.
In addition, this firmware contains the necessary logic for supporting iscsi & rdma, for which we plan on pushing protocol drivers in the imminent future.

qed: Introduce VFs
This adds the qed VFs for the first time - The vfs are limited functions, with a very different PCI bar structure [when compared with PFs] to better impose the related security demands associated with them.
This patch includes the logic neccesary to allow VFs to successfully probe [without actually adding the ability to enable iov]. This includes diverging all the flows that would occur as part of the pci probe of the driver, preventing VF from accessing registers/memories it can't and instead utilize the VF->PF channel to query the PF for needed information.

qed: Add VF->PF channel infrastructure
Communication between VF and PF is based on a dedicated HW channel; VF will prepare a messge, and by signaling the HW the PF would get a notification of that message existance. The PF would then copy the message, process it and DMA an answer back to the VF as a response.
The messages themselves are TLV-based - allowing easier backward/forward compatibility.
This patch adds the infrastructure of the channel on the PF side - starting with the arrival of the notification and ending with DMAing the response back to the VF.
It also adds a dummy-response as reference, as it only lays the groundwork of the communication; it doesn't really add support of any actual messages.
