usb: typec: tipd: add init and reset functions to tipd_data

The current implementation includes a number of special cases for the
tps25750. Nevertheless, init and reset functions can be generalized by
adding function pointers to the tipd_data structure in order to offer
that functionality to other parts without additional conditional
clauses.

Some functionality like the cold reset request (GAID) is shared by the
tps25750 and the tps6598x, so they can use the same reset function.
