SPIP is only used in S0, so keep the module disabled in lower power states. Disabling SPIP through spi_enable() will also restore our CS pin to ODR_HIGH. BUG=chrome-os-partner:56860 BRANCH=None TEST=Verify SPIP is functional on initial power-up, sysjump, and on apshutdown / re-power-on. Also verify GPIO_SPI_SENSOR_CS_L goes low in S5.
