soc: qcom: pmic_glink_altmode: Consume TBT3/USB4 mode notifications

Some compute SoCs support additional operation modes, extending the
existing set of USB3/safe/DP-alt-mode.

The firmware performs all the necessary handshakes for
us and there is no room for error on that level (i.e. the sequences
will match what happens on Windows).

The trade-off with that approach is that the received notifications
trim some of the PDO/EUDO data (particularly the cable/plug parts),
offering a set of similar-in-nature-but-not-the-same indicators.

In an attempt to remedy this, I reconstructed some of it, so that the
connected mux/retimer drivers can continue to behave as expected.

Add support for parsing the aforementioned data coming from PMIC_GLINK
and passing it on to the various Type-C components.
