ARM: dts: logicpd-torpedo-som: Remove twl_keypad

The TWL4030 used on the Logit PD Torpedo SOM does not have the
keypad pins routed. This patch disables the twl_keypad driver
to remove some splat during boot:

twl4030_keypad 48070000.i2c:twl@48:keypad: missing or malformed property linux,keymap: -22
twl4030_keypad 48070000.i2c:twl@48:keypad: Failed to build keymap
twl4030_keypad: probe of 48070000.i2c:twl@48:keypad failed with error -22
