drm/amd/display: replace fast_validate with enum dc_validate_mode

Browse Source 
[Why]
The boolean fast_validate is used as an
input parameter in multiple functions. To
support more scenarios, we are
replacing it with enum dc_validate_mode.

[How]
The enum dc_validate_mode introduces three
possible values:
1) DC_VALIDATE_MODE_AND_PROGRAMMING:
   Apply the mode to hardware
2) DC_VALIDATE_MODE_ONLY:
   Check whether the mode can be supported
3) DC_VALIDATE_MODE_AND_STATE_INDEX:
   Check if the mode can be supported, and
   determine the optimal voltage level
   needed to support it.
