The LDP uses both TWL4030 and GPIO's for its keypad inputs.
This patch changes the LDP board file to make use of both the TWL4030
and GPIO keypad drivers.

-/* OMAP3430 LDP Keymaps:
- * OMAP LDP uses both TWL4030 GPIO's and OMAP GPIO's to get key presses.
- * This is why there are two keymaps:
- * - ldp_twl4030_keymap (TWL4030)
- * - ldp_omap_gpio_keymap (OMAP GPIO's)
- * Unfortunately the input subsystem requires all the keymaps to be
- * listed in one place (.keymap) in order for a key to be a valid input.
- * This is why some keys appear in both keymaps.
- * If a key does appear in both keymaps then its entry in
- * ldp_twl4030_keymap is purely to keep the input subsystem happy and
- * its row/col values have no meaning.
