[WHY & HOW]
DCN401 is only supported using DML2.1, so remove unused code and files.

[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.

[WHY]
There are several gaps that can result in SubVP being enabled with
incompatible HW cursor sizes, and unjust restrictions to cursor size due
to wrong predictions on future usage of SubVP.

[HOW]
- remove "prediction" logic in favor of tagging based on previous SubVP
  usage
- block SubVP if current HW cursor settings are incompatible
- provide interface for DM to determine if HW cursor should be disabled
  due to an attempt to enable SubVP

[Why]
The minimum value of the dst_y_prefetch_equ was not correct
in prefetch calculation whice causes OPTC underflow.

[How]
Add the min operation of dst_y_prefetch_equ in prefetch calculation
for legacy DML.

[Why]

Urgent latency adjustment was disabled on DCN35 due to issues with P0
enablement on some platforms. Without urgent latency, underflows occur
when doing certain high timing configurations. After testing, we found
that reenabling urgent latency didn't reintroduce p0 support on multiple
platforms.

[How]

renable urgent latency on DCN35 and setting it to 3000 Mhz.
