drm/i915: Use the CRC gpio for panel enable/disable
The CRC (Crystal Cove) PMIC, controls the panel enable and disable
signals for BYT for dsi panels. This is indicated in the VBT fields. Use
that to initialize and use GPIO based control for these signals.
v2: Use the newer gpiod interface(Alexandre)
v3: Remove the redundant checks and unused code (Ville)
v4: Moved PWM vs SoC backlight #defines to intel_bios.h (Jani)
