Hi Linus,
 I had requested this from Sherman. The reason is so that pinctrl can
be selectable through defconfig, instead of through SoC select
statements. And the reason for that is so that, in the future, some of
these can be switched into loadable modules (which can't be done from
Kconfig). This will become necessary with the move to multiplatform -
we won't be able to have everything static anymore.

 Thanks,
   csd
