Add support for configuring it for various flavors of TBT3/USB4 operation.

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.

It usually sits between a USB/DisplayPort PHY and the Type-C connector, and provides orientation and altmode handling. The boards that use this retimer are the ones featuring the Qualcomm Snapdragon X Elite SoCs. Add a driver with support for the following modes: - DisplayPort 4-lanes - DisplayPort 2-lanes + USB3 - USB3 There is another variant of this retimer which is called PS8833. It seems to be really similar to the PS8830, so future-proof this driver by naming it ps883x.
