Use u16 instead of unsigned int to store pinmux enums, as they fit
easily in 16 bits.
This decreases the size of a (32-bit) shmobile_defconfig kernel
supporting 9 SoCs by 5780 bytes.
FIXME This doesn't make any difference on arm64, as all individual
objects are always 8-byte aligned by the compiler.

This is not the complete patch, as I don't want to spam you with a few
thousand lines of uninteresting changes.
