drm/amd/display: Fix idle optimization checks for multi-display and dual eDP

Browse source

[Why]
Idle optimizations are blocked if there's more than one eDP connector
on the board - blocking S0i3 and IPS2 for static screen.

[How]
Fix the checks to correctly detect number of active eDP.
Also restrict the eDP support to panels that have correct feature
support.
