soc/intel/skl/graphics: Implement panel setup

Logs from Linux' i915 suggest that not even the FSP/GOP takes proper
care of this. The sequence is mostly the same as on older platforms,
with a slightly different configuration of the backlight PWM.

We light the panel up with 50% PWM duty cycle. This often results in
an already rather high perceived brightness, but shouldn't be too
blinding.
