+[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.
