pwm-backlight: Enable/disable the PWM before/after LCD enable toggle.
commit 5fb5caee92ba35a4a3baa61d45a78eb057e2c031 upstream.
Before this patch the enable signal was set before the PWM signal and
vice-versa on power off. This sequence is wrong, at least, it is on
the different panels datasheets that I checked, so I inverted the sequence
to follow the specs.
For reference the following panels have the mentioned sequence:
- N133HSE-EA1 (Innolux)
- N116BGE (Innolux)
- N156BGE-L21 (Innolux)
- B101EAN0 (Auo)
- B101AW03 (Auo)
- LTN101NT05 (Samsung)
- CLAA101WA01A (Chunghwa)
