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 Cc: Shaoyun Liu <shaoyun.liu@amd.com> Reviewed-by: shaoyun.liu <shaoyun.liu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit 0180e0a5dd5c6ff118043ee42dbbbddaf881f283) Cc: stable@vger.kernel.org
