Keyboard: omap-keypad: use matrix_keypad.h

Most keypad drivers make use of the <linux/input/matrix_keypad.h>
defined macros, structures and inline functions.

Convert omap-keypad driver to use those as well, as suggested by a
compile time warning, hardcoded into the OMAP <palt/keypad.h>.

Created against linux-2.6.37-rc5.
Tested on Amstrad Delta.
Compile tested with omap1_defconfig and omap2plus_defconfig shrinked to
board-h4.
