drm/amd/display: Allow clock sharing b/w HDMI and DVI 



[why]
HDMI and DVI share the same PHY clock and single link
DVI and HDMI both use 4 lanes, so they should be allowed
to be sharing the same clock source if all other parameters
are satisfied.

[how]
Change a check for general DVI to Dual DVI.
