drm/i915/adlp/tc: Align the connect/disconnect PHY sequence with bspec

Browse source

Bspec has updated the TC connect/disconnect sequences, add the required
platform hooks for these.

The difference wrt. the old sequence is the order of taking the PHY
ownership - while holding a port power reference this requires - and
blocking the TC-cold power state.

Bspec: 49294
