[HACK NOTFORMERGE] PBP: Fix panel reset
On warm reset, the pinebook pro panel is not working correctly.
The issue is not yet debugged so, for now, this hack seems to be
enough. It toggles the GPIO1_C6 gpio [ LCDVCC_EN signal in the
schematics ] used by the vcc3v3_panel regulator.
There's no gpio_request, since the gpio is already in use at this
stage, so it can only fail.
