This series introduces a level of indirection between the controller's view of a typec_mux/switch and the implementation and then expands that to support multiple drivers. This is needed in order to support devices such as the Qualcomm Snapdragon 888 HDK, which does muxing and orientation handling in the QMP (USB+DP) PHY and SBU muxing in the external FSA4480 chip. Additionally integration of typec mux and switch in the QMP PHY is included in the series, as is the new FSA4480 driver. This is done to deal with the renaming of the driver-side typec_mux -> typec_mux_dev.
