lib/igt_amd: add helpers to check PSR state
[why]
For AMDGPU devices, we'd check the PSR state via reading from the
debugfs interface for a given eDP connector, where the debugfs
interface path locates at
<debugfs_root>/dri/0/eDP-X/psr_state
where 'X' is the eDP connector index.
[how]
define and add the helper to check if PSR state debugfs interface
is supported in driver, and the helper to read PSR state from the
debugfs interface.
