mb/google: Add more comment on GFX devices for the future reference
Add more details to instruct future boards/models implementers regarding
how GFX devices should be added.
If HDMI and DP connectors are enumerated by the kernel in
/sys/class/drm/ then corresponding GFX device should be added to ACPI.
It is possible that some connectors do not have dedicated ports, but
still enumerated.
The order of GFX devices is DDIA -> DDIB -> TCPX.
