Precedence: bulk

This adds the missing bits to support the USB-C Altmode
support on SM8550.

These are the following changes since the previous SM8450 SoC:
- No more GLINK altmode events for USB only changes, only DP
- Type-C orientation is available on a PMIC signal connected
  to a GPIO line
- When altmode is disconnected, an 0xff mode event is sent.

The 0xff altmode is translated as a SAFE type-c mux mode.

The fact No more GLINK altmode events for USB needs to be resolved
in a separate patchset.

Redriver driver & bindings dependency at [1].
