Input: pxa27x_keypad - introduce pxa27x_keypad_config()

Introduce pxa27x_keypad_config() for keypad registers configuration
and remove the reg_kpc, reg_kprec from platform data structure
so that configurations of keypad registers can be centralized to a
single function.

It can also be re-used when resuming.
