ARM: dts: msm: Suspend USB input for debug battery in SM8150 platforms

Currently on the detection of debug battery (e.g. battery id set
to 7.5 K), charger HW disables battery charging autonomously. In
addition to that, suspend USB input through SW so that the device
can be tested as per the requirement (not to source power from
the charger).
