Make i8042 independent of host <--> KBC bus.
This CL attempts to abstract underlying bus from i8042 code. Nearly
all i8042 logic is isolated already. This patch is intended to allow
us to use i8042 logic for processing keys and commands on boards which
do not necessarily use LPC as the host <--> KBC bus interface.
This CL does the following:
- Define KBC bus <--> host (kbc_host_bus) on a per-board basis in
board.c.
- Add generic wrappers in place of lpc_keyboard_* in i8042 code.
- Define the behavior of generic wrappers in EC-specific keyboard
sources. If board.c specifies LPC, then send via LPC.
TODO: This needs to be tested on real hardware...

BUG=None
TEST=Locally compiled for Link, BDS and Discovery.
