drm/amdgpu: handle more than 10 UVD sessions (v2)
Change History
--------------
v2:
- Make firmware version check correctly. Firmware
versions >= 1.80 should all support 40 UVD
instances.
- Replace AMDGPU_MAX_UVD_HANDLES with max_handles
variable.
v1:
- The firmware can handle upto 40 UVD sessions.
