kernel: bgmac: move bgmac patches already applied in mainline kernel to generic

The bgmac driver will be used on the brcm47xx and the bcm53xx target. 
These are only the patches already applied in current net-next/master
branch.

-bgmac: fix internal switch initialization
-
-Some devices (BCM4749, BCM5357, BCM53572) have internal switch that
-requires initialization. We already have code for this, but because
-of the typo in code it was never working. This resulted in network not
-working for some routers and possibility of soft-bricking them.
-
-Use correct bit for switch initialization and fix typo in the define.

-bgmac: implement unaligned addressing for DMA rings that support it
-
-This is important patch for new devices that support unaligned
-addressing. That devices suffer from the backward-compatibility bug in
-DMA engine. In theory we should be able to use old mechanism, but in
-practice DMA address seems to be randomly copied into status register
-when hardware reaches end of a ring. This breaks reading slot number
-from status register and we can't use DMA anymore.
