drm/amd/display: enabling seamless boot sequence for dcn2

[Why]
Seamless boot (building SW state inheriting BIOS-initialized timing) was
enabled on DCN2, including fixes

[How]
Includes fixes for MPC, DPPCLK, and DIG FE mapping/OTG source select/
Pixel clock.

This is part 2 of 2 for seamless boot NV10
