[PATCH 1/4] input: uapi: Add trigger_left and trigger_right to ff_rumble_effect struct

[Daniel Bomar]

Add 2 variables to the control the trigger motors into the struct that
gets passed in from userspace.

ff_rumble_effect is part of a union in ff_effect. This does not grow the
total size of the union so should be ABI compatible.
