drm/amd/display: Add option to configure mapping policy for edp0 on dp1

Browse Source 
[Why]
We want flexibility to choose how pwrseq instance is mapped to eDP panel

[How]
Add configuration option to choose the pwrseq mapping policy.
When enabled, allow fixed mapping between DIG inst to pwrseq inst.
