drm/amd/display: Expose OTG_V_TOTAL_MID for HW Diags

[Why]
Existing HW Features, HW Diags test requested that the
registers be exposed.

[How]
Add V_TOTAL_MID to existing DC structures.
Make sure values are passed down throughout DC
Add Register definition.
Program the additional registers
Add additional Logic for V_TOTAL_CONTROL.
