kernel: bgmac: backport patch switching to feature_flags

It was needed upstream to avoid bcma references in the main code. To
match this new code our patch adding SRAB was also updated.

Subject: [PATCH] net: bgmac: clarify CONFIG_BCMA dependency
The bgmac driver depends on BCMA_HOST_SOC, which is only used
when CONFIG_BCMA is enabled. However, it is a bool option and can
be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading
to an obvious link error:
drivers/built-in.o: In function `bgmac_init':
:(.init.text+0x7f2c): undefined reference to `__bcma_driver_register'
drivers/built-in.o: In function `bgmac_exit':
:(.exit.text+0x110a): undefined reference to `bcma_driver_unregister'
To avoid this case, we need to depend on both BCMA and BCMA_SOC,
as this patch does. I'm also trying to make the dependency more
readable by splitting it into three lines, and adding a COMPILE_TEST
alternative so we can test-build it in all configurations that
support BCMA.
The added dependency on FIXED_PHY addresses a related issue where
we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and
CONFIG_BGMAC=y.

Subject: [PATCH 4/5] net: ethernet: bgmac: convert to feature flags
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.
