dt-bindings: power: supply: ltc4162-l-charger: Add ltc4162-f/s and ltc4015

Add LTC4162-F/S and LTC4015 to the supported devices of LTC4162-L.
They share a common set of registers. The only differences lie in the
resolution value of the scaling factor for battery voltage and battery
current measurement, input voltage, and input current for different
battery chemistries. The differences also include the calculation of
setting and getting the actual voltage applied to the charge voltage,
as well as getting the die temperature.

This add compatible entries for ltc4162-f/s and ltc4015 and include
datasheets for new devices.
