[v2,0/4] usb: typec: ucsi: Expand power supply support

Message

Hi Heikki,

This series makes the following updates to the UCSI power supply
driver.

1. Adds support for the power supply status property.
2. Updates the driver to distinguish between PD and PD DRP power supply
types.
3. Adds the charge control limit max property which can be used to
request a PR swap from sysfs.
4. Fixes a simple SET_PRD typo in the ucsi.h header.

I've checked that the series builds on top of the usb-next branch and
manually tested functionality on top of a 6.10-rc5 ChromeOS kernel. Let
me know if you have any questions.

Thanks,
Jameson

Changes in V2
- Uses DRP bit in source PDOs for setting USB DRP power supply type.
- Adds SET_SINK_PATH call when handling an update to
charge_control_limit_max.
