soc/intel/tigerlake: Return TBT PowerResource from PR0 and PR3
TBT PowerResource _ON/_OFF methods are currently invoked by _PS0 and _PS3 respectively. It is defined for ACPI driver to call _ON and _OFF methods. This change drops the _PS0 and _PS3 call for _ON/_OFF and returns TBT PowerResource declaration in the _PR0 and _PR3, then ACPI driver will call the TBT PowerResource _ON and _OFF methods. BUG=b:188891878 TEST=Traced both of TBT _ON and _OFF methods invocation and execution at run time. Verified TBT's power_state to be D3Cold.
