drm/amdgpu/mes: add compatibility checks for set_hw_resource_1
Seems some older MES firmware versions do not properly support
this packet. Add back some the compatibility checks.
v2: switch to fw version check (Shaoyun)
Fixes: f81cd793119e ("drm/amd/amdgpu: Fix MES init sequence")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4295
