Hans Verkuil 15b4511a4a drm/vc4: add HDMI CEC support
This patch adds support to VC4 for CEC.  It is under a separate
Kconfig option to keep everyone using VC4 from needing to pull in the
CEC core.

Thanks to Eric Anholt for providing me with the CEC register information.

Choose this option if you have a system that has a Broadcom
VC4 GPU, such as the Raspberry Pi or other BCM2708/BCM2835.
This driver requires that "avoid_warnings=2" be present in
the config.txt for the firmware, to keep it from smashing
our display setup.

Choose this option if you have a Broadcom VC4 GPU
and want to use CEC.
