version in the future if we don't have FPU support. If CONFIG_FPU flag
is not set, fixed-point object temperature calculation would be used.

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.

Supports turning system on and off via power button.
Also added 'powerbtn' command, which sends a power button press of the
specified duration, and deprecated the 'x86power s0' command, since
pressing the power button is a more correct way of powering on/off the
system.
Note that current coreboot doesn't seem to boot reliably; when it
fails, the x86 asks for S5 and then S0 a second later. It boots about
every 3rd try. No indication this is due to the EC; the EC just was
ignoring these requests until this CL.
