usb: typec: fusb302: add DRM DP HPD bridge support
Add support to use fusb302 based USB-C connectors with the DP altmode
helper code on devicetree based platforms. To get this working there
must be a DRM bridge chain from the DisplayPort controller to the USB-C
connector. E.g. on Rockchip RK3576:
root@rk3576 # cat /sys/kernel/debug/dri/0/encoder-0/bridges
bridge[0]: dw_dp_bridge_funcs
refcount: 7
type: [10] DP
OF: /soc/dp@27e40000:rockchip,rk3576-dp
ops: [0x47] detect edid hpd
bridge[1]: drm_aux_bridge_funcs
refcount: 4
type: [0] Unknown
OF: /soc/phy@2b010000:rockchip,rk3576-usbdp-phy
ops: [0x0]
bridge[2]: drm_aux_hpd_bridge_funcs
refcount: 5
type: [10] DP
OF: /soc/i2c@2ac50000/typec-portc@22/connector:usb-c-connector
ops: [0x4] hpd
