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
