drm/i915: Backlight control using CRC PMIC based PWM driver
Use the CRC PWM device in intel_panel.c and add new MIPI backlight
specififc callbacks
v2: Modify to use pwm_config callback
v3: Addressed Jani's comments
- Renamed all function as pwm_* instead of vlv_*
- Call intel_panel_actually_set_backlight in enable function
- Return -ENODEV in case pwm_get fails
- in case pwm_config error return error cdoe from pwm_config
- Cleanup pwm in intel_panel_destroy_backlight
v4: Removed unused #defines and initialized backlight with INVALID_PIPE (Ville)
