[why]
When user unplugs mst hubs, the current code will forcefully zero
entire mst payload allocation table structure stored in link before we
deallocate actual payload when disabling stream.
During the first disable stream sequence, we will use current mst
payload allocation table to determine if link should be turned off.
Because we zero out it before we are disabling stream, the payload
allocation table stored in link doesn't represent the actual allocation status,
so we turn off link at the first disable stream without waiting until all
streams' payloads have been deallocated. This avoilates the designed
deallocation sequence and caused system hang in DP2 scenario.
[how]
Remove payload during deallocation and never zero payload allocation structure
without actually deallocating payload.

[why]
Original change 594b237b9a ("drm/amd/display: Add
interface to track PHY state") was implemented by assuming stream's
dpms off is equivalent to PHY power off.
This assumption doesn't hold in following situations:
1. MST multiple stream scenario, where multiple streams are sharing the
same PHY output. Toggle dpms off for one of the stream doesn't power
off the PHY due to the presence of other streams.
2. enable stream failure scenario, where enable stream fails due to
failure of link training. This will cause DPMS off is set to false, while
the actual PHY power state is off in certain cases.
Due to the problematic assumption, the logic will skip disabling
other streams for MST multiple stream scenario, therefore PHY is
not actually powered off.
[how]
1. Rework this refactor by moving PHY state update down to hardware
level, where we update PHY state in place when hardware sequencer
is actually changing the power state of the PHY hardware.
2. Reimplement symclk on TX off workaround in place when we are actually
calling transmitter control to power off PHY in dcn32. Note the workaround is
added due to the lack of proper software interface to set TX while keeping
symclk on. We plan to address this interface problem so we can set TX off
only without affecting symclk in future dcn versions.

[Why]
DC makes use of layer_index (zpos) when picking the HW plane to enable
HW cursor on. However, some compositors will not attach zpos information
to each DRM plane. Consequently, in amdgpu, we default layer_index to 0
and do not update it.
This causes said DC logic to enable HW cursor on all planes of the same
layer_index, which manifests as a double cursor issue if one of the
planes is scaled (and hence scaling the cursor as well).
[How]
Use DRM core helpers to calculate a normalized_zpos value for each
drm_plane_state under each crtc, within the atomic state.
This helper will first consider existing zpos values, and if
identical/unset, fallback to plane ID ordering.
The normalized_zpos is then passed to dc_plane_info during atomic check
for later use by the cursor logic.

420 modes are limited by FMT buffer width of 4096
which requires multi-pipe support in form of ODM
combine. If 420 modes have greater HActive than
4096, the DML logic should accomodate whether
it should be rejected, or ODM combine 2:1 or 4:1

FMT Buffer limit of 4096 in DCN32. Force ODM
combine depending on HActive and FMT Buffer limit.
Reject modes if TMDS 420 and above 4096.

To reduce the amount of stack space that

UseMinimumDCFCLK() as noinline, using the _for_stack variant for

Most of the arguments are identical between the two call sites and they
can be accessed through the 'struct vba_vars_st' pointer. This reduces
the total amount of stack space that
dml31_ModeSupportAndSystemConfigurationFull() uses by 112 bytes with
LLVM 16 (1976 -> 1864), helping clear up the following clang warning:

mixed with 'mode_lib->vba'.

[Why & How]
Fix the instatiation sequence for MPC registers and add a few other
missing register definitions that were ommited erroneously when copying
them over to enable runtime initialization of reigster offsets for
DCN32/321
