lib/igt_amd: refactor checker of debugfs interface existence

[why]
The existed amdgpu debugfs helpers to check existance/support of
connector's debugfs entry have a bunch of code redundant. Since
the generic debugfs interface checker is defined, we'd refactor
to avoid code redundancy.

[how]
- call generic helper igt_amd_output_has_debugfs() for debugfs
  interface existence check for DSC, HPD, LINK SETTING, PSR CAP
  etc.
- call psr state check helper for existed basic PSR test case.
