[PATCH RESEND] ARM: pxa27x_keypad: clear pending interrupts on keypad config

It behaves correctly, it just can't handle last keypress (because it's
booting Linux).
Even if it would be possible to fix this issue in bootloader it's
always nice to keep driver
failure-proof, so it does not fail even if bootloader left something
in non-consistent state.

True.
