[PATCH i-g-t] tests/intel/kms_pm_dc: Remove PKC10 dependecy to validate DC6

[Mohammed Thasleem]

DC6 counter was removed MTL onwards, so pkc10 counter is used
to validated DC6 tests but with the new approach of kmd changes
created DC6 debugfs entry counter to validated DC6 tests and
removeing the existing pkc10 code.
