Input: pcf50633-input - remove the driver 

The pcf50633 was used as part of the OpenMoko devices but the support
for its main chip was recently removed in: commit 61b7f892 ("ARM:
s3c: remove all s3c24xx support")

Remove the input driver.

This was originally posted as a set of pcf50633 removals in March,
and is the only major component that hasn't been picked up.
