[PATCH] pinctrl: PINCTRL_STMFX should depend on CONFIG_OF

[Timur Tabi <ttabi@nvidia.com>]

Commit e785c990adcc ("pinctrl: Kconfig: drop unneeded dependencies
on OF_GPIO") removed a redundant dependecy on CONFIG_OF_GPIO for
several pinctrl drivers, but this change also removed a dependency
on CONFIG_OF for some of those drivers.

Normally, this wouldn't be a problem, but PINCTRL_STMFX also selected
MFD_STMFX, which does depend on CONFIG_OF.  This conflict allows
MFD_STMFX to be enabled even if CONFIG_OF is disabled.

Fix this by also having PINCTRL_STMFX depend on CONFIG_OF.  This is
okay because the pinctrl-stmfx driver actually does depend on CONFIG_OF
functions.
