net: phy: broadcom: Register dummy IRQ handler
In order to have our interrupt descriptor fully setup and in particular the action, ensure that we register a full fledged interrupt handler. This also allow us to set the interrupt polarity and flow through the same call.
This is specifically necessary for kernel/irq/pm.c::suspend_device_irq to set the interrupt descriptor to the IRQD_WAKEUP_ARMED state and enable the interrupt for wake-up since it was still in a disabled state.
Without an interrupt descriptor we would have ran into cases where the wake-up interrupt is not capable of waking up the system, specifically if we resumed the system ACPI S5 using the Ethernet PHY. In that case the Ethernet PHY interrupt would be pending by the time the kernel booted, which it would acknowledge but then we could never use it as a wake-up source again.

net: phy: broadcom: Add support for Wake-on-LAN
Add support for WAKE_UCAST, WAKE_MCAST, WAKE_BCAST, WAKE_MAGIC and WAKE_MAGICSECURE. This is only supported with the BCM54210E and compatible Ethernet PHYs. Using the in-band interrupt or an out of band GPIO interrupts are supported.
Broadcom PHYs will generate a Wake-on-LAN level low interrupt on LED4 as soon as one of the supported patterns is being matched. That includes generating such an interrupt even if the PHY is operated during normal modes. If WAKE_UCAST is selected, this could lead to the LED4 interrupt firing up for every packet being received which is absolutely undesirable from a performance point of view.
Because the Wake-on-LAN configuration can be set long before the system is actually put to sleep, we cannot have an interrupt service routine to clear on read the interrupt status register and ensure that new packet matches will be detected.
It is desirable to enable the Wake-on-LAN interrupt as late as possible during the system suspend process such that we limit the number of interrupts to be handled by the system, but also conversely feed into the Linux's system suspend way of dealing with interrupts in and around the points of no return.

net: phy: broadcom: implement generic .handle_interrupt() callback
In an attempt to actually support shared IRQs in phylib, we now move the responsibility of triggering the phylib state machine or just returning IRQ_NONE, based on the IRQ status register, to the PHY driver. Having 3 different IRQ handling callbacks (.handle_interrupt(), .did_interrupt() and .ack_interrupt() ) is confusing so let the PHY driver implement directly an IRQ handler like any other device driver. Make this driver follow the new convention.

net: phy: broadcom: add cable test support
Most modern broadcom PHYs support ECD (enhanced cable diagnostics). Add support for it in the bcm-phy-lib so they can easily be used in the PHY driver.
There are two access methods for ECD: legacy by expansion registers and via the new RDB registers which are exclusive. Provide functions in two variants where the PHY driver can choose from. To keep things simple for now, we just switch the register access to expansion registers in the RDB variant for now. On the flipside, we have to keep a bus lock to prevent any other non-legacy access on the PHY.
The results of the intra-pair tests are inconclusive (at least for the BCM54140). Most of the times half the length is reported but sometimes the length is correct.

net: phy: broadcom: Fix bcm_write_exp()
On newer PHYs, we need to select the expansion register to write with setting bits [11:8] to 0xf. This was done correctly by bcm7xxx.c prior to being migrated to generic code under bcm-phy-lib.c which unfortunately used the older implementation from the BCM54xx days.
Fix this by creating an inline stub: bcm_write_exp_sel() which adds the correct value (MII_BCM54XX_EXP_SEL_ER) and update both the Cygnus PHY and BCM7xxx PHY drivers which require setting these bits.
broadcom.c is unchanged because some PHYs even use a different selector method, so let them specify it directly (e.g: SerDes secondary selector).

Broadcom PHYs expose a number of PHY error counters: receive errors, false carrier sense, SerDes BER count, local and remote receive errors. Add support code to allow retrieving these error counters. Since the Broadcom PHY library code is used by several drivers, make it possible for them to specify the storage for the software copy of the statistics.

net: phy: broadcom: add cable test support Most modern broadcom PHYs support ECD (enhanced cable diagnostics). Add support for it in the bcm-phy-lib so they can easily be used in the PHY driver. There are two access methods for ECD: legacy by expansion registers and via the new RDB registers which are exclusive. Provide functions in two variants where the PHY driver can choose from. To keep things simple for now, we just switch the register access to expansion registers in the RDB variant for now. On the flipside, we have to keep a bus lock to prevent any other non-legacy access on the PHY. The results of the intra-pair tests are inconclusive (at least for the BCM54140). Most of the times half the length is reported but sometimes the length is correct.

net: phy: broadcom: add exp register access methods without buslock Add helper to read and write expansion registers without taking the mdio lock. Please note, that this changes the semantics of the read and write. Before there was no lock between selecting the expansion register and the actual read/write. This may lead to access failures if there are parallel accesses. Instead take the bus lock during the whole access cycle.
