This patch allows for GPIOs specified in the devicetree to be used as SPI chipselects on TI OMAP2 SoCs.
Tested on the AM3354.
v4: Breaks patch down into patch series.
v3: Switches driver to use transfer_one instead of transfer_one_message allowing the spi core to handle toggling GPIO chip selects if specified.
v2: Considers the possible use of SPI_CS_HIGH during chip select activation.
