usb: typec: ptn36502: Only select DRM_AUX_BRIDGE with OF

CONFIG_DRM_AUX_BRIDGE depends on CONFIG_OF but that dependency is not
included when CONFIG_TYPEC_MUX_PTN36502 selects it, resulting in a
Kconfig warning when CONFIG_OF is disabled:

WARNING: unmet direct dependencies detected for DRM_AUX_BRIDGE
Depends on [n]: HAS_IOMEM [=y] && DRM_BRIDGE [=y] && OF [=n]
Selected by [m]:
- TYPEC_MUX_PTN36502 [=m] && USB_SUPPORT [=y] && TYPEC [=m] && I2C [=y] && (DRM [=y] || DRM [=y]=n) && DRM_BRIDGE [=y]

Only select CONFIG_DRM_AUX_BRIDGE when CONFIG_DRM_BRIDGE and CONFIG_OF
are enabled to clear up the warning. This results in no functional
change because prior to the refactoring that introduces this warning,
ptn36502_register_bridge() returned 0 when CONFIG_OF was disabled, which
continues to occur with drm_aux_bridge_register() when
CONFIG_DRM_AUX_BRIDGE is not enabled.

usb: typec: mux: add Qualcomm WCD939X USB SubSystem Altmode Mux driver

Qualcomm WCD9390/WCD9395 is a standalone Hi-Fi audio codec IC with a
functionally separate USB SubSystem for Altmode/Analog Audio Switch
accessible over an I2C interface.

It provides switching USB-C USB2.0 lines between USB and Audio Headphones
speaker lines, and the USB-C SBU lines between DisplayPort AUX and Audio
Headphones Microphone/Ground.

The Audio Headphone and Microphone data path between the Codec and the
USB-C Mux subsystems are external to the IC, thus requiring DT
port-endpoint graph description to handle USB-C altmode & orientation
switching for Audio Accessory Mode.

usb: typec: mux: Introduce GPIO-based SBU mux

switch the orientation of the SBU lines in USB Type-C applications.

This introduces a generic driver, which implements the typec_switch and
typec_mux interfaces to perform these operations.

The ON Semiconductor FSA4480 is a USB Type-C port multimedia switch with
support for analog audio headsets. It allows sharing a common USB Type-C
port to pass USB2.0 signal, analog audio, sideband use wires and analog
microphone signal.

Due to lacking upstream audio support for testing, the audio muxing is
left untouched, but implementation of muxing the SBU lines is provided
as a pair of Type-C mux and switch devices. This provides the necessary
support for enabling the DisplayPort altmode on devices with this
circuit.
