matrix_keyboard_of_fill_keymap() routines allocates memory using kzalloc()

This patch converts these kzalloc() calls to devm_kzalloc() and thus we don't
require matrix_keyboard_of_free_keymap() anymore.

But that said, Dmitry specifically requested that the devm_* function
not be used during initial review of this code; IIRC he preferred just
doing the explicit frees. I can't find a link right now though.
