[PATCH 2/4] Input: mms114 - mark as direct input device

[Dmitry Torokhov]

mms14 is a touchscreen and thus a direct input device; let's mark it
as such. This also allows us to drop some initialization code as
input_init_mt_slots() will do that for us.

Also add error handling for input_mt_init_slots().
