ARM: dts: msm: update liquid 8996 battery and charger configuration

Liquid uses the sanyo-7560mAh battery. Update the charger node to reflect
that.

Liquid also has external mux which chooses between USB port on the
device and docking station and feeds the higher priority path to the
usbin of the pmi charger. The USB driver defaults to SDP type and uses
a gpio for detecting USB presence. The pmi charger need not notify the
USB driver of the presence and type. Use the skip-usb-notification
property for liquid.
