[PATCH i-g-t v3 1/4] tests/intel/kms_pm_dc: Update test_deep_pkgc_state function

[Naladala Ramanaidu]

Enhanced the test_deep_pkgc_state function to includes the
following changes:
- Removed the unused variable `vrr_supported` to clean up the code.
- Added a check for the eDP connector to ensure proper connector handling.
- Implemented a check to ensure frame time is not less than 5ms.
- Added logic to disable VRR if VRR is enabled.

v2: Correct indentation and update comments. (Suraj, Jeevan)
v3: Update Commit subject/message. (Kamil)
