arm64: dts: qcom: sdm845-oneplus-*: set constant-charge-current-max-microamp

Set the maximum constant charge current to use for this battery. While
the battery is likely comfortably capable of 4A or so, OnePlus didn't
include a secondary charger IC for parallel charging (instead they have
their proprietary Dash Charging). It's possible that this value could be
safely increased after some testing (and when we have support for
modelling the charger as a cooling device properly), but for now this
value is acceptable.

This is references from qcom,usb-icl-ua property in the downstream
vendor devicetree.
