Input: samsung-keypad - properly state IOMEM dependency

BugLink: https://bugs.launchpad.net/bugs/1964361
commit ba115adf61b36b8c167126425a62b0efc23f72c0 upstream.

Make the samsung-keypad driver explicitly depend on CONFIG_HAS_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'
