drm/amd/display: Revert Remove pixle rate limit for subvp

[ Upstream commit cf8c498694a443e28dc1222f3ab94677114a4724 ]

This reverts commit 340383c734f8 ("drm/amd/display: Remove pixle rate
limit for subvp")

[why]
The original commit causes a regression when subvp is applied
on ODM required 8k60hz timing. The display shows black screen
on boot. The issue can be recovered with hotplug. It also causes
MPO to fail. We will temprarily revert this commit and investigate
the root cause further.

[ Upstream commit 2ff33c759a4247c84ec0b7815f1f223e155ba82a ]

[why]
Originally, PMFW said min FCLK is 300Mhz, but min DCFCLK can be increased
to 400Mhz because min FCLK is now 600Mhz so FCLK >= 1.5 * DCFCLK hardware
requirement will still be satisfied. Increasing min DCFCLK addresses
underflow issues (underflow occurs when phantom pipe is turned on for some
Sub-Viewport configs).

[Description]
When choosing which dummy p-state latency to use, we
need to use the DRAM speed from validation. The DRAMSpeed
DML variable can change because we use different input
params to DML when populating watermarks set B.

drm/amd/display: implement pipe type definition and adding accessors

[why]
There is a lack of encapsulation of pipe connection representation in pipe context.
This has caused many challenging bugs and coding errors with repeated
logic to identify the same pipe type.

[how]
Formally define pipe types and provide getters to identify a pipe type and
find a pipe based on specific requirements. Update existing logic in non dcn
specific files and dcn32 and future versions to use the new accessors.

drm/amd/display: Refactor recout calculation with a more generic formula

[Why]
Current recout calculation has a few assumptions and implementation
for MPO + ODM combine calculation is very specific. The equation has
too many cases without enough comments to document the detail.

[How]
The change remove the following assumptions:
1. When MPO is enabled, we only allow ODM Combine 2:1
2. ODM Combine always has even segment width.
3. Secondary MPO plane's pipe_ctx copies pre_odm_pipe from
its top pipe.

The change applies a generic formula with more details in comment to
document this solution so it is eaiser to learn and debug later.

drm/amd/display: SubVP high refresh only if all displays >= 120hz

[Description]
- SubVP high refresh should only be enabled if all displays
are >= 120hz. We do not want to accidentally enables configs
such as 60hz[SubVP] + 120hz[SubVP]
- Ensure that the SubVP config generation code does not produce
configs such as 60hz[SubVP] + 120hz[SubVP]
- Also add admissibility checks to ensure these configs do not
pass as valid configs
