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.
In order to handle those changes, a new orientation-gpios property
is added to the usb-c connector bindings.
The 0xff altomode is translated as a SAFE type-c mux mode.
And in order to handle such info, we tie this to the UCSI connector
events to propagate the orientation to Type-C switches.
