Introduce a typec_orientation in qmp_combo and fill out the various "placeholders" with the associated logic. By initializing the orientation to "normal" this change has no functional impact, but reduces the size of the upcoming introduction of dynamic orientation switching.

Register a typec_switch device to allow a TCPM to configure the orientation. The newly introduced orientation variable is adjusted based on the request, and the initialized components are brought down and up again. To keep track of what parts needs to be cycled new variables to keep track of the individual init_count is introduced. Both the USB and the DisplayPort altmode signals are properly switched. For DisplayPort the controller will after the TCPM having established orientation power on the PHY, so this is not done implicitly, but for USB the PHY typically is kept initialized across the switch, and must therefor then be reinitialized. This is based on initial work by Wesley Cheng.

The TCPM needs to be able to convey the HPD signal to the DisplayPort controller, but no directly link is provided by DeviceTree so the signal needs to "pass through" the QMP combo phy. Handle this by introducing a drm_bridge which upon initialization finds the next bridge (i.e. the usb-c-connector) and chain this together. This way HPD changes in the connector will propagate to the DisplayPort driver. The connector bridge is resolved lazily, as the TCPM is expected to be able to resolve the typec mux and switch at probe time, so the QMP combo phy will probe before the TCPM.
