[PATCH] drm/amdgpu/mes: add compatibility checks for set_hw_resource_1

[Liu, Shaoyun]

[AMD Official Use Only - AMD Internal Distribution Only]

Maybe  it's better to use the  MES FW version . Here is what I got from the  MES release.
For nv3x : 0x50
For nv4x : 0x4b

Regards

Seems some older MES firmware versions do not properly support this packet.  Add back some the compatibility checks.
