dt-bindings: qcom,battery-charger: Add qcom,ship-mode-immediate property

Currently, charger FW configures and enables ship mode in parallel with
shutdown activity. This can cause a race condition leaving the device in
a bad state if the device is powering down while SW is still issuing SPMI
writes.

Add new "qcom,ship-mode-immediate" property to flag that ship mode should
be immediately configured after user sets ship_mode_en to avoid this
race condition.
