This patchset updates the ADLP TypeC PHY connect/disconnect sequences
that changed in Bspec. The change in the power domains used and order of
enabling these wrt. taking the PHY ownership domains requires moving
these sequences to platform specific hooks; the first part of the
patchset adds these along with other hooks to setup/query the PHY HW
state, replacing the corresponding if ladders.
The second part of the patchset adds the ADLP specific hooks, updating
the connect/disconnect sequences and hotplug detection for it according
to bspec.
The last part makes sure that the port DPLL is disabled before
disconnecting the TC PHY, as required by bspec.
Tested on ICL, TGL, ADLP.
