ANX7688 is a typec port controller that also converts HDMI to DP. ANX7688 is found on Acer Chromebook R13 (elm) and on Pine64 PinePhone.
On Acer Chromebook R13, the device is powered-up and controller by the Embedded Controller. Therefore the dt-bindings requires only the 'compatible' and 'reg' properties.
In v4 of this set, the device was added as an 'mfd' device and an additional 'bridge' device for the HDMI-DP conversion, see [1]. In this version we add the device as a typec controller.

Changes from v4: Send the device as a typec controller instead of mfd. The bridge driver should therefore convert from a platform driver to an i2c driver.
