Allow lid-less configuration
power_button_x86.c and switch.c assume there is a lid switch. This
patch separate them so that a board with power button but with no
lid can be configured properly.
This patch also moves backlight control to the board directory
so that only the boards with a backlight turn it on/off when power
state changes.
BUG=none
BRANCH=none
TEST=boot fizz. make buildall.
