Subject: [PATCH] Input: select INPUT_MATRIXKMAP for lpc32xx-keys

This patch adds a "select" dependency of KEYBOARD_LPC32XX on INPUT_MATRIXKMAP,
as the other drivers are doing in this regard. This fixes the following compile
error if KEYBOARD_LPC32XX is enabled but INPUT_MATRIXKMAP is not:

drivers/input/keyboard/lpc32xx-keys.c:230: undefined reference to
`matrix_keypad_build_keymap'
