The monitored-battery property is a property of the board, not the PMIC.
Move this property to the DTS of its only user, sp9860g-1h10.
While at it, disable the fuel-gauge node by default and enable it only
for its users, as it requires board-specific properties to work correctly.

Looks reasonable to me. Thanks.

Changes in V2:
- none

Note that the 'sprd,calib-resistance-micro-ohms' property isn't specified
as I do not have the board or any other source of information about it.

If the SPRD folks could chime in here, that'd be great.
