drm/amd/display: Bump the HDMI clock to 340MHz
[Why]
DP-HDMI dongles can execeed bandwidth requirements on high resolution
monitors. This can lead to pruning the high resolution modes.
HDMI 1.3 bumped the clock to 340MHz, but display code never matched it.
[How]
Set default to (DVI) 165MHz. Once HDMI display is identified update
to 340MHz.
