Remove an old mistake of mine. This has sneak in the code i sent to gonzo
at that time, but AFAIK it is only used on routerboards.
Enabling GPIO_FUNC_SPI_CS[1|2]_EN will claim the use of gpio pins 0 and 1
respectivelly for use as SPI CS pins.
When really needed, this can still be enabled on kernel hints using the
function_set and function_clear knobs.
