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. Redriver driver & bindings dependency at [1].
