mtd: rawnand: brcmnand: Add BCMA shim
Add a BCMA shim to allow us to register the brcmnand driver using the
BCMA bus which provides indirect memory mapped access to SoC registers.
There are a number of registers that need to be byte swapped because
they are natively big endian, coming directly from the NAND chip, and
there is no bus interface unlike the iProc or STB platforms that
performs the byte swapping for us.
