Add a simple battery node to the p4note device tree to set the missing
values for the charger to work properly.

Squash this change with the previous patch. No need to add a line and
immediately change it in next patch.

These commits go via different paths and are loosely related, so the
moment this is applied, the SMB347 charger is not yet in P4Note DTS.
Just write that SMB347 is being used by P4Note family of devices, e.g.
Samsung Galaxy Note 10.1 (GT-N8010/N8013).
