[PATCH] drm/arm/hdlcd: Take over EFI framebuffer properly

[Robin Murphy]

The Arm Juno board EDK2 port has provided an EFI GOP display via HDLCD0
for some time now, which works nicely as an early framebuffer. However,
once the HDLCD driver probes and takes over the hardware, it should
take over the logical framebuffer as well, otherwise the now-defunct GOP
device hangs about and virtual console output inevitably disappears into
the wrong place most of the time.
