This patch saves off the original value of force_dsc_en and
restores it back after each test and in the igt exit handler
so that it gets restored on any failure/assertion.

DSC enable gets configured during compute_config and needs
a full modeset to force DSC.
Sometimes in between the tests, if the initial output is same as the
mode being set for DSC then it will not do a full modeset.
So we disable the output before forcing a mode with DSC enable.

The test leaves the debugfs flag enabled if the driver failed to enable
DSC. And as it turns out, the feature gets enabled only after the test
completes and consequently affects PSR2 tests that follow. Let's make sure
the test cleans up correctly, even though the DSC test itself needs to be
fixed.
Also included some formatting fixes within the function.

This patch adds a basic kms test to validate the display stream
compression functionality if supported on DP/eDP connector.
Currently this has only two subtests to force the DSC on all
the eDP and DP connectors that support it with default parameters.
This will be expanded to add more subtests to tweak DSC parameters.
v8 (from Manasi):
* Fix the logic to scan through all connectors even if some dont
support DSC/FEC (Petri)
* Fix the skip test logic if no connectors support DSC to avoid
false positives (Petri)
* Move test clenup to run_test
v7: (from Anusha)
* Code Style changes.(Petri)
* Use for_each_pipe() instead of for_each_pipe_static().(Petri)
* Correct logic by avoiding skipping of inner for loop completely.(Petri)
v6: (from Anusha)
* Fix run_test() (Petri)
* Fix update_display() to avoid leaks. (Petri)
v5:
* Fix test cleanup to avoid crash (Petri)
v4:
* Future proof for more test types (Petri)
* Fix alphabetical order (Petri)
* s/igt_display_init/igt_display_require (Petri)
* Remove blank lines after return (Petri)
v3:
* Use array of connectors and loop through (Petri)
* Also check for FEC on DP connectors (Manasi)
* Add a Pipe_A restriction on DP (Ville)
v2:
* Use IGT wrappers for all (DK, Antonio)
* Split into two subtests for eDP and DP types (Petri)
