On TI DaVinci's SPI controller, the SPIDAT1 register which controls the chip slect status, also has data transmit register in the lower 16 bits. Writing to the whole 32-bits triggers an additional data transmit every time the chip select is disabled. While most SPI slaves cope-up with this, some cannot. This patch fixes this by doing a 16-bit write on the upper half of the SPIDAT1 register While at it, group the SPIGCR1 register related defines seperately from SPIDAT1 register defines.
