Add the description for the display panel found on this phone and remove
the simple-framebuffer that was in place until now. Unfortunately the
LCDB module on PM6150L isn't yet supported upstream so we need to use a
dummy regulator-fixed in the meantime.
And with this done we can also enable the GPU.
