drm/i915: disable CPU PWM also on LPT/SPT backlight disable
Although we don't support or enable CPU PWM with LPT/SPT based systems,
it may have been enabled prior to loading the driver. Disable the CPU
PWM on LPT/SPT backlight disable to avoid warnings on LCPLL disable.
The issue has been present on BDW since BDW enabling, but was recently
introduced on HSW with
