Rename extra_dw to extra_bytes and document what it's for.
The value is already used as if it were bytes in vcn_v4_0.c
and in amdgpu_ring_init. Just adjust the dword count in
jpeg_v1_0.c so that it becomes a byte count.
v2:
Rename extra_dw to extra_bytes as discussed during review.

Add mmio_remap bookkeeping to amdgpu_device and introduce
amdgpu_ttm_mmio_remap_bo_init()/fini() to manage a kernel-owned,
one-page (4K) BO in AMDGPU_GEM_DOMAIN_MMIO_REMAP.
Bookkeeping:
- adev->rmmio_remap.bo : kernel-owned singleton BO
The BO is allocated during TTM init when a remap bus address is available
(adev->rmmio_remap.bus_addr) and PAGE_SIZE <= AMDGPU_GPU_PAGE_SIZE (4K),
and freed during TTM fini.
v2:
- Check mmio_remap bus address (adev->rmmio_remap.bus_addr) instead of
rmmio_base. (Alex)
- Skip quietly if PAGE_SIZE > AMDGPU_GPU_PAGE_SIZE or no bus address
(no warn). (Alex)
- Use `amdgpu_bo_create()` (not *_kernel) - Only with this The object
is stored in adev->mmio_remap.bo and will later be exposed to
userspace via a GEM handle. (Christian)
v3:
- Remove obvious comment before amdgpu_ttm_mmio_remap_bo_fini() call.
(Alex)
v4:
- Squash bookkeeping into this patch (Christian)

Add a one-page TTM range manager for AMDGPU_PL_MMIO_REMAP via
amdgpu_ttm_init_on_chip(). This only registers the placement with TTM;
no BO is allocated in this patch.
The singleton 4K remap BO is created and freed in the following patch.
This split follows to separate heap bring-up from BO allocation.

Implement TTM-level behavior for AMDGPU_PL_MMIO_REMAP so it behaves as a
CPU-visible IO page:
* amdgpu_evict_flags(): mark as unmovable
* amdgpu_res_cpu_visible(): consider CPU-visible
* amdgpu_bo_move(): use null move when src/dst is MMIO_REMAP
* amdgpu_ttm_io_mem_reserve(): program base/is_iomem/caching using
the device's mmio_remap_* metadata
* amdgpu_ttm_io_mem_pfn(): return PFN for the remapped HDP page
* amdgpu_ttm_tt_pde_flags(): set AMDGPU_PTE_SYSTEM for this mem type
v2:
- Drop HDP-specific comment; keep generic remap (Alex).
v3:
- Fix indentation in amdgpu_res_cpu_visible (Christian).
- Use adev->rmmio_remap.bus_addr for MMIO_REMAP bus/PFN calculations
(Alex).
v4:
- Drop unnecessary (resource_size_t) casts in MMIO_REMAP io-mem paths

The CSB buffer manipulation occurs in memory where the BO is mapped
during initialization, and some references to this buffer are handled
with volatile, which is incorrect in this scenario. There are a few
cases where the use of volatile is accepted, but none of them align with
CSB operations. Therefore, this commit removes all the volatile
variables associated with the CSB code.

Before exporting a buffer, make sure it has been populated with
pages at least once.
While discussing cgroups we noticed a problem where you could export
a BO to a dma-buf without having it ever being backed or accounted for.
This meant in low memory situations or eventually with cgroups, a
lower privledged process might cause the compositor to try and allocate
a lot of memory on it's behalf and this could fail. At least make
sure the exporter has managed to allocate the RAM at least once
before exporting the object.
This only applies currently to TTM_PL_SYSTEM objects, because
GTT objects get populated on first validate, and VRAM doesn't
use TT.

When examining the VCN function init, it is common to find a loop that
initializes VCN rings, which uses one IRQ per instance. However, VCN
4.0.3 deviates from this pattern, as it includes a distinct field to
differentiate instances, which results in a slightly different ring
init. This commit makes this difference explicit by using a fixed index
when initializing the ring buffer and also adds a comment.

Current mem limit check leaks some GTT memory (reserved_for_pt
reserved_for_ras + adev->vram_pin_size) for small APUs.
Since carveout VRAM is tunable on APUs, there are three case
regarding the carveout VRAM size relative to GTT:
1. 0 < carveout < gtt
apu_prefer_gtt = true, is_app_apu = false
2. carveout > gtt / 2
apu_prefer_gtt = false, is_app_apu = false
3. 0 = carveout
apu_prefer_gtt = true, is_app_apu = true
It doesn't make sense to check below limitation in case 1
(default case, small carveout) because the values in the below
expression are mixed with carveout and gtt.
adev->kfd.vram_used[xcp_id] + vram_needed >
vram_size - reserved_for_pt - reserved_for_ras -
atomic64_read(&adev->vram_pin_size)
gtt: kfd.vram_used, vram_needed, vram_size
carveout: reserved_for_pt, reserved_for_ras, adev->vram_pin_size
In case 1, vram allocation will go to gtt domain, skip vram check
since ttm_mem_limit check already cover this allocation.

Align the function headers for `amdgpu_max_hdmi_pixel_clock` and
`amdgpu_connector_dvi_mode_valid` with the function implementations so
they match the expected kdoc style.
Fixes the below:
