[PATCH v1] pinctrl: Kconfig: fix unmet direct dependencies detected for MFD_STMFX

[Haiyue Wang <haiyuewa@163.com>]

The commit e785c990adcc ("pinctrl: Kconfig: drop unneeded dependencies
on OF_GPIO") will cause:

WARNING: unmet direct dependencies detected for MFD_STMFX
  Depends on [n]: HAS_IOMEM [=y] && I2C [=y] && OF [=n]
  Selected by [m]:
  - PINCTRL_STMFX [=m] && PINCTRL [=y] && I2C [=y] && HAS_IOMEM [=y]

PINCTRL_STMFX selects MFD_STMFX, which depends on OF. Previously this
was gated transitively by OF_GPIO, which is dropped. So PINCTRL_STMFX
can be enabled on non-OF systems and select MFD_STMFX in violation of
its OF requirement. Add the missing "depends on OF".
