drm/amd/display: Default HDMI6G support to true. Log VBIOS table error.

Can you see if this helps? Our Windows driver definitely checks the HDMI6G flag
from VBIOS but it will default to allow 6G on HDMI if the VBIOS check fails.

This patch is porting the same behavior in the hopes that it will help with
your issue.

If this patch works a dmesg log with the amdgpu.dc_log=1 option on the kernel
would help us understand the root cause a bit better.

If it doesn't work it's back to the drawing board for me.
