[Why]
Implement an interface to obtain plane size caps
[How]
Add min_width, min_height fields to dc_plane_cap structure.
Set values to 16x16 for discrete ASICs, and 64x64 for others.

Fix build error by protecting code with config guard
to enable building amdgpu without CONFIG_DRM_AMD_DC_DCN

[Why&How]
Accessing dcn20_add_dsc_to_stream_resource directly
causes build failure for configuration which has
CONFIG_DRM_AMD_DC_DCN disabled. Fix this by
calling the corresponding function exposed via dc
resource functions.

[why]
On DCN20, Some features would not be activated when ALLM was turned on.
TV seemed to activate only the latest info packet sent, and the ALLM
info packet was sent after the VSIF info packet.
The packet indices was also inconsistent between DCN10 and DCN20.
[how]
Change the packet indices of DCN20 to match those of DCN10.
This makes them consistent and also makes the vendor info packet
be sent after the hfvsif info packet.

[Why]
dcn20_add_dsc_to_stream_resource is accessed in amdgpu_dm directly.
This creates build error for configuration with DCN disabled.
[How]
Make the function available through a resource pool function so
that dcn20 function need not be called directly.

[Why]
With ABM implemented on DMUB the ABM enablement
shoudn't be solely rely on dmcu. Otherwise it won't work
if dmcu is disabled.
[How]
1. Decouple dmcub config copy from dmcu iram copy.
2. Set abm connector property if either dmcu or dmub enabled.

outstanding log reaches threshold will trigger IH ring1/2's wptr
reported, that will avoid generating interrupts to ring0 too frequent.
But if ring1/2's wptr hasn't been increased for a long time, the outstanding log
can't reach threshold so that driver can't get latest wptr info and
miss some interrupts.

Per designs, the swSMU code is separated into four layers. And the typical
calling flow should be like: amdgpu_smu.c -> ${asic}_ppt.c -> smu_v11/12_0.c
-> smu_cmn.c. Compile errors will come out for any violations. This can
help to prevent cross callings(e.g. amdgpu_smu.c -> ${asic}_ppt.c ->
amdgpu_smu.c -> ${asic}_ppt.c) which were common in our code.

All of the drivers in the kernel tree only call this from one of the
following contexts:
* drm_crtc_funcs->reset
* During initial module load
Since both of these contexts are guaranteed to have interrupts enabled
beforehand, there's no need to use the irqsave/irqrestore variants of
spin_(un)lock(). So, fix this to make the irq context of this function
more obvious.

The original intention was to avoid CPU page table unmaps
when BOs move between the GTT and SYSTEM domain.
The problem is that this never correctly handled changes
in the caching attributes or backing pages.
Just drop this for now and simply unmap the CPU page
tables in all cases.

Nouveau is the only user of this functionality and evicting io space
on -EAGAIN is really a misuse of the return code.
Instead switch to using -ENOSPC here which makes much more sense and
simplifies the code.
This could unbreak something as we now cleanly return EAGAIN, but the
chance for this are rather low.
