Replace simple-KMS helpers with regular atomic-modesetting helpers.
The simple-KMS helpers introduce a mid-layer abstraction without
added functionality. Using regular atomic helpers makes the driver's
implementation more discoverable and simplifies code sharing.
The conversion effectively open-codes the simple-KMS functions and
data structure within udl. No functional changes.
v2:
* don't use the atomic_disable plane helper

amdkfd_total_mem_size is the size of total GPUs vram plus system memory
to estimate page tables memory usage and leave enough VRAM room for page
tables allocation.
Calculate amdkfd_total_mem_size in amdgpu_amdkfd_device_probe is
incorrect because adev->gmc.real_vram_size is still 0 called from
amdgpu_device_ip_early_init. Move the calculation
to amdgpu_amdkfd_device_init to get the correct VRAM size.

DCN provides a hook to check if we can have a new pipe allocation based
on some DC constraints. If the current configuration supports the new
pipe request, DC updates its context; otherwise, it will keep the same
configuration. This behavior is similar across multiple ASICs, and for
this reason, we reused DCN20 on DCN321. However, this DCN32x has some
peculiarities which require its function to avoid weird pipe split
issues. This commit update this issue by using
