Add a power supply driver that supports charge thresholds and behaviour
configuration.

This is a complete rework of
"platform/chrome: cros_ec_framework_laptop: new driver" [0], which used
Framework specific EC commands.

The driver propsed in this series only uses upstream CrOS functionality.

Tested on a Framework 13 AMD, Firmware 3.05.
