dev: Fix i8042 device errors

The patch that added M5_FALLTHROUGH (5c41076bd7610 misc: Updates for gcc7.2
for x86) incorrectly added breaks to the i8042 device without implementing
the correct functions. This patch implements keyboard writes, but ignores
output writes.

Note: Without this patch Linux 4.14 won't boot.
