[PATCH v2] pinctrl/coh901: use clk_prepare_[en|dis]able()

[Linus Walleij]

From: Linus Walleij <linus.walleij@xxxxxxxxxx>

The COH901 GPIO driver did not prepare or unprepare its
clock, so let us fix it to do so.

ChangeLog v1->v2:
- Fix up to use clk_disable_unprepare() on error and exit paths,
  noticed by Pankaj Jangra.
