omap_uwire: SPI_CPHA mode bugfix
The omap_uwire controller driver handles SPI_CPHA incorrectly;
It should mean:
CPHA=0 ... sample at leading edge of clock
CPHA=1 ... sample at trailing edge of clock
This bug has been masked by inverse bugs in layered drivers;
and was uncovered by running some of them on non-OMAP hardware.
