Nitro is the embedded version of the ethernet controller in the North
Star 2 SoC. Add basic code to recognize the chip ID and disable
the features (ntuple, TPA, ring and port statistics) not supported on
Nitro A0.

This reverts commit 4386f5662e63 ("net: ethernet: bcmgenet: use
phy_ethtool_{get|set}_link_ksettings")
This patch is wrong, the function phy_ethtool_{get|set}_link_ksettings
don't check if the device is running, but the driver bcmgenet need this
check.
The function {get|set}_settings need to access the mdio bus, and this
bus may only be used when the device is running. Otherwise, the clock
is disable and a mdio access will fail.

The bcma portion of the driver has been split off into a bcma specific
driver. This has been mirrored for the platform driver. The last
references to the bcma core struct have been changed into a generic
function call. These function calls are wrappers to either the original
bcma code or new platform functions that access the same areas via MMIO.
This necessitated adding function pointers for both platform and bcma to
hide which backend is being used from the generic bgmac code.

The bgmac driver is using the bcma provides device ID and revision, as
well as the SoC ID and package, to determine which features are
necessary to enable, reset, etc in the driver. In anticipation of
removing the bcma requirement for this driver, these must be changed to
not reference that struct. In place of that, each "feature" has been
given a flag, and the flags are enabled for their respective device and
SoC.

Move the BCMA MDIO phy into a separate file, as it is very tightly
coupled with the BCMA bus. This will help with the upcoming BCMA
removal from the bgmac driver. Optimally, this should be moved into
phy drivers, but it is too tightly coupled with the bgmac driver to
effectively move it without more changes to the driver.
Note: the phy_reset was intentionally removed, as the mdio phy subsystem
automatically resets the phy if a reset function pointer is present. In
addition to the moving of the driver, this reset function is added.

Calling the firmware to do function reset on the PF will kill all the VFs.
To prevent that, we call function reset on the 1st PF open before any VF
can be activated. On subsequent PF opens (with possibly some active VFs),
a bit has been set and we'll skip the function reset. VF driver will
always do function reset on every open. If there is an AER event, we will
always do function reset.
