epicmtd: Remap hardware arrow keys.

Remap keys from a landscape perspective to a portrait
perspective, so that it can be properly rotated by the
system depending on the screen orientation.

Required with the merge of patch
http://review.cyanogenmod.org/#/c/50214/ which removed
the requirement for keyboard.orientationAware to
be set in an idc file, thus exposing the flawed keymapping.
