drm/bridge: Add ChromeOS EC ANX7688 bridge driver support
This driver adds support for the ChromeOS EC ANX7688 HDMI to DP converter
For our use case, the only reason the Linux kernel driver is necessary is
to reject resolutions that require more bandwidth than what is available
on the DP side. DP bandwidth and lane count are reported by the bridge via
2 registers and, as far as we know, only chips that have a firmware
version greater than 0.85 support these two registers.
