drm/amd/display: Fix PSR-SU not support but still call the amdgpu_dm_psr_enable
[Why] The enum DC_PSR_VERSION_SU_1 of psr_version is 1 and DC_PSR_VERSION_UNSUPPORTED is 0xFFFFFFFF. The original code may has chance trigger the amdgpu_dm_psr_enable() while psr version is set to DC_PSR_VERSION_UNSUPPORTED. [How] Modify the condition to psr->psr_version == DC_PSR_VERSION_SU_1 Reviewed-by: Sun peng Li <sunpeng.li@amd.com> Signed-off-by: Tom Chung <chiahsuan.chung@amd.com> Signed-off-by: Roman Li <roman.li@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit f765e7ce0417f8dc38479b4b495047c397c16902) Cc: stable@vger.kernel.org
