[ARM] pxa: add partial keypad support for mainstone
This is partial because mainstone's keypad is really special, some of the keys like '1', '2', ... are actually connected to two row/column juntions, thus pressing '1' is equivalent to pressing 'A' & 'H'. This is really brain damanged since it makes distinguishing between pressing '1' and multiple keys pressing of 'A' & 'H' difficult. So these special keys are not supported for the time being.
