BCM6338 and BCM6348, and BCM6358 and everything after that share the
same register layout. To not have to redefine them for each new chip
and keep the code size small, only use the definitions for the first

This commit causes a race between PCI scan and SSB fallback SPROM handler
registration, causing the wifi to not work on slower systems. The only
subsystem touched from board_register_devices is platform device
registration, which is safe as an arch init call.

We cannot use __init for earlyprintk code or data, since the kernel
parameter "keep_bootcon" allows leaving the boot console enabled.

Currently MIPS will crash/hang/die if you use keep_bootcon. The patch
fixes it at least on Lemote FuLoong mini-PC. Changes for other boards
were done based on what I could find with grep...

While calculating the mac address the pointer for the current octet was
never reset back to the least significant one after being decremented
because of an octet overflow. This resulted in the code continuing to
increment at the current octet, potentially generating duplicate or
invalid mac addresses.

As a second issue the pointer was allowed to advance up to the most
significant octet, modifying the OUI, and potentially changing the type
of mac address.

Rewrite the code so it resets the pointer to the least significant
in each outer loop step, and bails out when the least significant octet
of the OUI is reached.

BCM6338 and BCM6348 have a message control register width of 8 bits, instead
of 16-bits like what the SPI driver assumes right now. Also the SPI message
type shift value of 14 is actually 6 for these SoCs.
This resulted in transmit FIFO corruption because we were writing 16-bits
to an 8-bits wide register, thus spanning on the first byte of the transmit
FIFO, which had already been filed in bcm63xx_spi_fill_txrx_fifo().

Fix this by passing the message control register width and message type
shift through platform data back to the SPI driver so that it can use
it properly.
