[igt-dev] [PATCH i-g-t v3] tests/i915/kms_dsc: add limited flag

[Swati Sharma <swati2.sharma@intel.com>]

Add limited flag to restrict test execution to one valid pipe-output
combination. By default all tests will run on all valid pipe-output
combinations.

v2: -rename extended to limited (Kamil)
v3: -add -l in help_str (Zbigniew)
    -remove static from data_t (Zbigniew)
