Add the devicetree binding for the Analog Devices LT8491, a high
voltage buck-boost battery charge controller with an I2C interface.
The values of the PCB resistors used by the chip's telemetry are
described as properties.

Add support for the Analog Devices LT8491 buck-boost battery charge
controller connected over I2C. The driver registers a power supply
exposing the charging status, battery voltage, current, power and
temperature, and the battery temperature limits. The PCB resistor
values needed by the chip's telemetry are read from the devicetree and
written to the chip at probe.
