arch/x86: Clean up mxt224 platform data

BZ: 20624

Remove useless platform data functions for mxt224 touchcreen
driver. Let the driver take defaults one instead.

Remove valid_interrupt function since it is the exact same than
driver's default one.
Remove init_platform_hw and exit_platform_hw functions since
they are empty.
