Subject: [PATCH v2 0/4] Google Pixel 6 (oriole): max77759 fuel gauge
 enablement and driver support

The Google Pixel 6 has a Maxim max77759 which provides a fuel gauge with
an interface with a lot in common with the Maxim max1720x.

Modify the Maxim max1720x driver to be compatible with the Maxim max77759 and
enable it for the gs101-oriole board.
