The cros_usbpd-charger already supports limiting input current, so we
can easily extend it as a passive thermal cooling device. By limiting
the current flow into the system, we can reduce the heat generated by
related chips, which results in reserving more thermal budget for the
system.

This series will only works on making it a OF style thermal cooling
device, so related code are guarded by #ifdef macros.

Changes in v2:
- Revise commit message for including the reason of change for this
  series.
- Remove uses of `ifdef CONFIG_THERMAL_OF`, and use
  `IS_ENABLED(CONFIG_THERMAL_OF)` when needed.
- Does not failing the driver probing if failed to register the usbpd
  device as a cooling device.
