usb: typec: ps883x: Cache register settings, not Type-C mode

Certain Type-C mode configurations may result in identical settings of
the PS8830. Check if the latter have changed instead of assuming
there's always a difference.

ps883x_set() is changed to accept a typec_retimer_state in preparation
for more work and the ps883x_sw_set() (which only handles orientation
switching) is changed to use regmap_assign_bits(), which itself does
not perform any writes if the desired value is already set.
