drm/amd/display: Update DTBCLK for DCN32

Browse source

[ Upstream commit 128c1ca030 ]

[Why&How]
- Implement interface to program DTBCLK DTO’s
  according to reference DTBCLK returned by PMFW
- This is required because DTO programming
  requires exact DTBCLK reference freq or it could
  result in underflow
