usb: typec: ucsi: register with power_supply class
With this change the UCSI device will show up in
/sys/class/power_supply/. The following values are exported:
- online
- usb_type
- voltage_min
- voltage_max
- voltage_now
- current_max
- current_now
Once a PD-capable type-C power source is connected to the system, GET_PDOS
UCSI command is used to query all source capabilities. Request data object
(RDO) is used to get current values.
