tests/amdgpu/amd_psr: define reusable wrapper for PSR support check

[why & how]
For amdgpu PSR-SU test cases, we'd first check if the sink device
and amdgpu driver support the PSR-SU feature at the beginning. We
define a local helper to wrap the check for PSR-SU support from
sink and driver as well and called by both MPO and FFU test case,
to avoid the code repetition.
