The minnie devices comes with an AUO B101EAN01 panel which is different
from default veyron devices, thus the power on/off timing sequence is
slightly different. The datasheet specifies a pwm delay of 200 ms, so
update the pwm-delay-us accordingly.

Heiko,
 I'm not able to test this patch in a minnie device because I don't have
one, so could you do a quick try, please?

Thanks,
 Enric

Changes since v1:
 - Add this new patch as minnie has differents timings.
