spi2_pins_a doesn't mean anything without any context.

Anyone should be able to read this commit log alone and understand
what it's about and why you are doing it.

It's clearly not the case here.

You should probably name that group spi2_pins_a. It feels a bit weird
to have a spi2_pins_b group without its "a" counterpart.

That patch should be merged with the patch 3, and since there's only
spi2 in use on that board, it should be aliased to spi0.
