Refactor the i8042 module to be thread-safe.
Any command/data coming from host will be placed in from_host queue, and
the interrupt handler returns immediately. The i8042_command_task() will
handle them later.
Data reply to the host will be protected by the mutex.
BUG=chrome-os-partner:10090
TEST=randomly play around on the link board.
