This makes the assumption that setting up pinctrl in cpu_init_r() is safe.
On samus we need GPIOs before relocation in order to support power control.
This commit fixes the following message on boot:

   initcall sequence ffe5c6f4 failed at call ffe01d3d (err=-1)
   ### ERROR ### Please RESET the board ###

In any case it seems better to leave init to driver model, so that it can
pick up the GPIO driver when it needs it. Since pinctrl is a dependency of
the GPIO driver, we may as well put the dependency there and avoid these
problems.
