spi: Eliminate the spi_cs_activate and spi_cs_deactivate functions.

They were only used internal to the SPI drivers and, according to the comment
next to their prototypes, were for when the SPI controller doesn't control the
chip select line directly and needs some help.

BUG=None
TEST=Built for link, falco, and rambi. Built and booted on peach_pit and nyan.
BRANCH=None
