Some ld9040 panels do not start without providing power control sequence during initialization. The patch fixes the driver by providing such sequence for all panels.

I've applied this to my drm/panel/for-next branch. Judging by the commit description this isn't a critical bug fix, so not a candidate for -fixes at this point.
