baytrail: initialize backlight PWM frequency
In order to protect ourselves from the kernel driver not honoring or
placing the correct frequency in the backlight register always set one.
This code path picks 200Hz as the default if nothing is specified in
device tree. It's somewhat arbitrary but that frequency is valid for all
the eDP panel specs we've seen being used on baytrail devices.
BUG=chrome-os-partner:28267
BRANCH=baytrail
TEST=Built and booted in normal mode. Noted register write stuck.
