After the IRQ deadlock issue is solved, I can finally offer the supporting
of the eDP panel sold by the T-CHIP Firefly.

I don't think it is necessary to enable two vop for a eDP panel, even
the vop lite is enough for the resolution of this panel.

I have verified those patch with the kmssink from Gstreamer.
but I still got a few warnings message, those message comes from booting time.

You may need the following patch to make PWM backlight work, or merge it
into the bootloader.
