power: supply: core: add UAPI to discover currently used extensions
Userspace wants to now about the used power supply extensions,
for example to handle a device extended by a certain extension
differently or to discover information about the extending device.
Add a sysfs directory to the power supply device.
This directory contains links which are named after the used extension
and point to the device implementing that extension.
