platform/x86: ayaneo-ec: Move Ayaneo devices from oxpec to ayaneo-ec

Currently, the oxpec driver contains Ayaneo devices. Move them to the
new ayaneo-ec driver, which is dedicated to them.

As this driver supports charge inhibition for Ayaneo, add support for it
for the AIR, AIR 1S, AB05-Medoncino, AIR Pro, and Kun, referenced from
the out-of-tree ayaneo-platform driver.

In addition, update the readmes of oxpec to reflect this change.
