555.42.02 has incompatible changes to FBSR.
At the same time, move the calling of FBSR functions from the instmem

With minimal to no direct HW programming required, most nvkm_engine
implementations are nearly identical when running on top of GSP-RM.
Add a common implementation of the boilerplate, and use nvkm_rm_gpu to
expose the correct class IDs.
As they're now handled by common code, and there's no support for them
prior to GSP-RM support - this deletes the GA100 NVDEC/NVJPG/OFA HALs,
the GA102 NVENC/OFA HALs, and the AD102 GR/NVDEC/NVENC/NVJPG/OFA HALs.

With GSP-RM handling the majority of the HW programming, NVKM's usual
HALs are more elaborate than necessary, resulting in a fair amount of
duplicated boilerplate.
Adds 'nvkm_rm_gpu' which serves to provide GPU-specific constants and
functions in a more streamlined manner.
This is initially used in subsequent commits to store engine class IDs,
and replace the per-engine/engobj boilerplate with common code for all
GSP-RM supported engines - and is further extended when adding GH100,
GB10x and GB20x support.

In order to specify a channel ID to RM during channel allocation, the
channel ID is broken down into a "userd page" index and an index into
that page.
It was assumed that RM would enforce that the same physical block of
memory be used for all CHIDs within a "userd page", and the GSP paths
override NVKM's normal CHID allocation to handle this.
However, none of that turns out to be necessary.
Remove the GSP-specific code and use the regular CHID allocation path.

Section .static_call_sites holds data structures that need to be sorted and
processed only at module load time. This initial processing happens in
static_call_add_module(), which is invoked as a callback to the
MODULE_STATE_COMING notification from prepare_coming_module().
The section is never modified afterwards. Make it therefore read-only after
module initialization to avoid any (non-)accidental modifications.

The MLX5_IB_STAGE_UAR stage in the RDMA driver is redundant and should
be removed.
Responsibility for initializing the device's UAR pointer
(mdev->priv.uar) lies with mlx5_core, which already sets it during the
mlx5_load() process.
At present, the RDMA UAR stage overwrites this pointer, which was
correctly initialized by mlx5_core, creating the risk of inconsistency.
Ownership and management of the UAR pointer should remain exclusively
within mlx5_core.
In the current upstream code, we luckily receive the same pointer, since
mlx5_get_uars_page() still finds available BF registers for that UAR,
allowing it to be shared.
However, future changes in mlx5_core may expose this flaw.
For instance, if mlx5_alloc_bfreg() is invoked twice before the RDMA UAR
stage runs, the RDMA driver may overwrite the UAR allocated by
mlx5_core.
This could lead to real bugs. For example, if mlx5_ib is unloaded
