drm/panel: ld9040: Use better magic values

Browse Source 
I have no idea what the prior magic values mean, and I have no idea
what my replacement (extracted from [1]) magic values mean.

What I do know, is that these new values result in a much better
picture, where the blacks are really black (as you would expect on an
AMOLED display) instead of grey-ish.
