[PATCH] Input: twl4030_keypad - drop support for platform data

[Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>]

Support for platform data from dropped from twl in 4a346a03a63c ("mfd:
twl: Remove platform data support") and board files were dropped even
earlier. There are no in-kernel users of twl4030_keypad_data in the
kernel, and the driver supports configuration via generic device
properties.

Drop support of static platform data from the keypad driver.
