When booting a board that does not have a keypad (such as imx6q-sabresd) the
following error is seen on boot:
imx-keypad 
20b8000.kpp: OF: linux,keymap property not defined in /soc/aips-bus@
02000000/kpp@
020b8000
imx-keypad 
20b8000.kpp: failed to build keymap
imx-keypad: probe of 
20b8000.kpp failed with error -2
Let's disable the keypad functionality in the dtsi files and let each board dts
enable it when needed.
