For DPX mode, the number of memory partitions supported should be less
than or equal to 2.

Add a callback interface to get the resource information of a partition
mode. Presently the information has number of resources and number of
entities sharing the resource.
Add the implementation for aquavanjaram SOCs.

Fix instance mask calculation for VCN IP. There are cases where VCN
instance could be shared across partitions. Fix here so that other
blocks don't need to check for any shared instances based on partition
mode.

This commit applies isolation enforcement to the GFX and Compute rings
in the gfx_v9_4_3 module.
The commit sets `amdgpu_gfx_enforce_isolation_ring_begin_use` and
`amdgpu_gfx_enforce_isolation_ring_end_use` as the functions to be
called when a ring begins and ends its use, respectively.
`amdgpu_gfx_enforce_isolation_ring_begin_use` is called when a ring
begins its use. This function cancels any scheduled
`enforce_isolation_work` and, if necessary, signals the Kernel Fusion
Driver (KFD) to stop the runqueue.
`amdgpu_gfx_enforce_isolation_ring_end_use` is called when a ring ends
its use. This function schedules `enforce_isolation_work` to be run
after a delay.
These functions are part of the Enforce Isolation Handler, which
enforces shader isolation on AMD GPUs to prevent data leakage between
different processes.
The commit also includes a check for the type of the ring. If the type
of the ring is `AMDGPU_RING_TYPE_COMPUTE`, the `xcp_id` of the
`enforce_isolation` structure in the `gfx` structure of the
`amdgpu_device` is set to the `xcp_id` of the ring. This ensures that
the correct `xcp_id` is used when enforcing isolation on compute rings.
The `xcp_id` is an identifier for an XCP partition, and different rings
can be associated with different XCP partitions.

For SOCs with GFX v9.4.3, a VF may have multiple compute partitions.
Fetch the partition information during init and initialize partition
nodes. There is no support to switch partition mode in VF mode, hence
disable the same.

On GFXIP9.4.3, make CPX mode as the default compute mode if the node is
setup in NPS4 memory partition mode. This change is only applicable for
dGPU, for APU, continue to use TPX mode.

rings with scheduler. It could result in out of bound access as total
