This value was verified by comparing register dumps of the MAX77693
charger with on mainline with a downstream kernel under Android; the
value on downstream was set to 1.8 amps when charging with a proper
charger.
Add it to a new battery node and pass it to the MAX77693 charger
so that the fast charge current setting can be used for charging.
