[PATCH 1/2] pinctrl: stmfx: fix mfd dependency

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

The PINCTRL_STMFX driver attempts to force-enable its MFD parent
driver, which is really the wrong way around compared to general
conventions. After the OF_GPIO dependency got dropped, this leads
to a harmless but annoying build warning:

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]

Change the 'select' into a dependency instead. As this changes the
defconfig behavior, also change the generic arm defconfig file to enable
the other symbol instead.

Fixes: e785c990adcc ("pinctrl: Kconfig: drop unneeded dependencies on OF_GPIO")
