Florian Fainelli 5a6704454a MIPS: BCM63xx: Fix SPI message control register handling for BCM6338/6348.
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.
