[PATCH i-g-t 3/3] tests/intel/kms_psr2_sf: extend tests for panel replay sf

[Kunal Joshi <kunal1.joshi@intel.com>]

Extend the tests to cover panel replay selective fetch feature.

From kms_psr2_sf test point of view we have check_pr_psr2_sel_fetch_support
function to check if PR/PSR2 selective fetch is supported for an output
if output supports selective fetch then we check we enter DEEP_SLEEP mode
in run function

v2: fixed dynamic test name
v3: use check_psr2_support (Jouni)
v4: correct order of checks in check_pr_psr2_sel_fetch_support (Jouni)
    use appropriate psr mode in psr_wait_entry (Jouni)
v5: use static in get_psr_mode_str_for_output (Jouni)
