Subject: [PATCH] Input: samsung-keypad - Properly state IOMEM dependency

Make the samsung-keypad driver explicitly depend on CONFIG_IOMEM, as it
calls devm_ioremap(). This prevents compile errors in some configs (e.g,
allyesconfig/randconfig under UML):

/usr/bin/ld: drivers/input/keyboard/samsung-keypad.o: in function `samsung_keypad_probe':
samsung-keypad.c:(.text+0xc60): undefined reference to `devm_ioremap'
