tegra124: modify panel init sequence
Panel datasheet defines some delay between PWM signal out and
backlight enable. This change fixes the current sequence
and makes the delays adjustable by dt setting.
BRANCH=none
BUG=chrome-os-partner:28008
TEST=Verified on Big DVT and Nyan/Norrin panels.
Panel works fine with dev mode, and the measurement
of power on sequence meets panel requirements.
