drm/amd/display: calculate psr config settings in runtime in DM

[why]
Currently the psr configuration parameters are hardcoded before
feeding into the DC helper before passing to DMUB FW. We'd rework
to call a shared helper to calculate/update generic psr config
fields which are relying on the stream timing and eDP sink PSR
caps to avoid hard-coding.

[how]
- drop part of hard-coded psr config fields by replacing w/ the
  call of helper from DM before feeding into DC link setup psr
  helper
- For those DM specific psr config fields, e.g. allow smu opt, is
  not to be set/updated from the shared helper but to rely on the
  DC feature mask
- for the psr version field in psr_config structure, since only
  the field psr_version of DC link psr_settings matters for that
  fed to DMUB FW, thus no need to set/update the psr_version field
  of psr_config structure.
