rockchip/spi: Allow SPI buses > 2

If SPI_BASEx is defined (for 2 < x <= 5), allow selecting it.
Since the bus number translates into an offset into an array, require
that all earlier buses are defined, too.

Also assert() that the array is properly sized instead of blindly
exceeding its bounds when called with a too big bus number.

TEST=initializing bus 5 doesn't trap anymore on kevin
BRANCH=none
BUG=none
