-Replace drm function call with existing library functions
-igt_display_reset() before all subtests
v2: -Move conversion to dynamic subtest to a separate patch (Bhanu)
-Use igt_output_get_mode to get default mode (Bhanu)
-Add 'is_atomic' check before igt_display_commit2 (Bhanu)
v3: -Move test_init after the checks to skip subtest (Bhanu)
-Update the logic to call make_fb() in test_init()
v4: -Move patch after patch to convert tests to dynamic to avoid code
duplicaton. (Bhanu)
v5: -Update commit message. (Bhanu)
-Move skip checks in the dynamic subtests before the start of the
subtest to optimize the test. (Bhanu)
-Close drm_fd at the end of the subtest.
v6: -Fix identation for braces. (Andre)
