ARM: pxa: add gpio keys information
Switching from corgikbd to matrixkbd corgi has lost support for few switches. Readd them through gpio-keys-polled device (-polled, since scoop does not provide IRQ for GPIO). Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com>
