Add the BQ25896 charge controller's missing pins which may make the schematic a bit ambiguous, reduce the value of the VBAT_REG LED's current limiting resistor to 1k in order to make it a bit brighter

This commit is thanks to our design reviewer's feedback.

VBAT(ovp_default)=REG06[7:2]=4.208V (reduce to 4.192V [010110])\nWorst Case:\nVBAT(default_max_ovp)=(REG06[7:2]×1.005)×1.04=4.3982016V\nBQ29705 provides 4.425V as OVP!
