mfd: pcF50633-gpio: Remove unused driver

Browse Source 
The pcf50633 was used as part of the OpenMoko devices but
the support for its main chip was recently removed in:
commit 61b7f8920b ("ARM: s3c: remove all s3c24xx support")

See https://lore.kernel.org/all/Z8z236h4B5A6Ki3D@gallifrey/

Remove it.

Say yes here if you want to include support GPIO for pins on
the PCF50633 chip.
