Jesse Zhang 78d0a27ae0 drm/amdgpu: Add user queue instance count in HW IP info
This change exposes the number of available user queue instances
for each hardware IP type (GFX, COMPUTE, SDMA) through the
drm_amdgpu_info_hw_ip interface.

Key changes:
1. Added userq_num_instance field to drm_amdgpu_info_hw_ip structure
2. Implemented counting of available HQD slots using:
   - mes.gfx_hqd_mask for GFX queues
   - mes.compute_hqd_mask for COMPUTE queues
   - mes.sdma_hqd_mask for SDMA queues
3. Only counts available instances when user queues are enabled
   (!disable_uq)

v2: using the adev->mes.gfx_hqd_mask[]/compute_hqd_mask[]/sdma_hqd_mask[] masks
  to determine the number of queue slots available for each engine type (Alex)
v3: rename userq_num_instance to userq_num_hqds (Alex)

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
