drm/amdgpu: Map/Unmap MMIO_REMAP as BAR register window; add TTM sg helpers; wire dma-buf

MMIO_REMAP (HDP flush page) exposes a hardware MMIO register window via
a PCI BAR; there are no struct pages backing it (not normal RAM).  But
when one device shares memory with another through dma-buf, the receiver
still expects a delivery route—a list of DMA-able chunks—called an
sg_table. For the BAR window, we can’t (no pages!), so we instead create
a one-entry list that points directly to the BAR’s physical bus address
and tell DMA: “use this I/O span.” - A single, contiguous byte range on
the PCI bus (start DMA address + length)). That’s why we map it with
dma_map_resource() and set sg_set_page(..., NULL, ...). Perform DMA
reads/writes directly to that range so we build an sg_table from a BAR
physical span and map it with dma_map_resource().

This patch centralizes the BAR-I/O mapping in TTM and wires dma-buf to
it:

Add amdgpu_ttm_mmio_remap_alloc_sgt() /
amdgpu_ttm_mmio_remap_free_sgt(). They walk the TTM resource via
amdgpu_res_cursor, add the byte offset to adev->rmmio_remap.bus_addr,
build a one-entry sg_table with sg_set_page(NULL, …), and map/unmap it
with dma_map_resource().

In dma-buf map/unmap, if the BO is in AMDGPU_PL_MMIO_REMAP, call the new
helpers.

Single place for BAR-I/O handling: amdgpu_ttm.c in
amdgpu_ttm_mmio_remap_alloc_sgt() and ..._free_sgt().
No struct pages: sg_set_page(sg, NULL, cur.size, 0); inside
amdgpu_ttm_mmio_remap_alloc_sgt().
Minimal sg_table: sg_alloc_table(*sgt, 1, GFP_KERNEL); inside
amdgpu_ttm_mmio_remap_alloc_sgt().
Hooked into dma-buf: amdgpu_dma_buf_map()/unmap() in amdgpu_dma_buf.c
call these helpers for AMDGPU_PL_MMIO_REMAP.

drm/amdgpu/ttm: Pin 4K MMIO_REMAP Singleton BO at Init v2

MMIO_REMAP (HDP flush page) is a hardware I/O window exposed via a PCI
BAR.  It must not migrate or be evicted.

Allocate a single 4 KB GEM BO in AMDGPU_GEM_DOMAIN_MMIO_REMAP during TTM
initialization when the hardware exposes a remap bus address and the
host page size is <= 4 KiB. Reserve the BO and pin it at the TTM level
so it remains fixed for its lifetime. No CPU mapping is established
here.

On teardown, reserve, unpin, and free the BO if present.

This prepares the object to be shared (e.g., via dma-buf) without
triggering placement changes or no CPU-access migration

Documentation/gpu: Add documentation about ring buffer

AMDGPU heavily relies on ring buffers to manage its components; as a
result, it has an elaborate mechanism of operation with multiple details
around it. This commit introduces new documentation on ring buffers,
detailing their management and expanding the explanation of Enforce
isolation. Finally, this commit also adds the documentation available in
the amdgpu_ring.c file to it.

Revert "drm/amd: Skip power ungate during suspend for VPE"

Skipping power ungate exposed some scenarios that will fail
like below:

```
amdgpu: Register(0) [regVPEC_QUEUE_RESET_REQ] failed to reach value 0x00000000 != 0x00000001n
amdgpu 0000:c1:00.0: amdgpu: VPE queue reset failed
...
amdgpu: [drm] *ERROR* wait_for_completion_timeout timeout!
```

The underlying s2idle issue that prompted this commit is going to
be fixed in BIOS.
This reverts commit 2a6c826cfeedd7714611ac115371a959ead55bda.
