Input: omap-keypad - drop optional GPIO support

Browse Source 
The driver supports passing some GPIO lines for rows and columns
through the driver data, but there is no in-kernel user of this.

Further the use seems convoluted because the GPIO lines are unused
in the driver, then explicitly free:ed when removing it without
being requested when probing it, which is assymetric and just
a recepie for disaster.

Remove the support for these unused GPIOs, if need be support can
be reestablished in an organized fashion using GPIO descriptors.
