Changed the zmk,battery-voltage-divider and zmk,battery-nrf-vddh drivers
to support only SENSOR_CHAN_VOLTAGE, and changed the default battery
fetch mode to ZMK_BATTERY_REPORTING_FETCH_MODE_LITHIUM_VOLTAGE. This
allowed for removing the copy of lithium_ion_mv_to_pct() from the
driver code, leaving only the version in battery.c.
Custom boards/shields that use a fuel gauge driver instead of a voltage
sensor, will need the following added to their Kconfig.defconfig:
choice ZMK_BATTERY_REPORTING_FETCH_MODE
default ZMK_BATTERY_REPORTING_FETCH_MODE_STATE_OF_CHARGE
endchoice
Alternatively, add the following to the _defconfig file:
ZMK_BATTERY_REPORTING_FETCH_MODE_STATE_OF_CHARGE=y
