[Intel-gfx] [PATCH v2 2/2] drm/i915/selftests: Convert atomic_* API calls for i915_active.count refcount_*

[Deepak R Varma]

Handle the struct i915_active member variable count transition from
atomic_t type to refcount_t type for selftest use cases. Transition the
atomic_*() API calls to their equivalent refcount_*() API calls.

Please note:
   1. Proposed changes are compile tested only.
   2. This patch 2/2 is required to be applied after patch 1/2 due to
      inter dependency.

Changes in v2:
   1. Patch added to patch series.
   2. Handle build issues Reported-by: kernel test robot <l...@intel.com>
      Include changes for i915/selftests use cases for atomic_* to refcount_*
      transition.
