Support for Battery Status & Battery Caps messages in response to
Get_Battery_Status & Get_Battery_Cap request is required by USB PD devices
powered by battery, as per "USB PD R3.1 V1.8 Spec", "6.13 Message
Applicability" section. This patchset adds support for these AMSes
to achieve greater compliance with the spec.

Changes in v2:
- Instead of introducing new "fixed-batteries" property to pass
reference to FG, use OF graph by extending "ports" property
definition. (suggested by Krzysztof).
- Demonstration of binding usage in gs101-oriole will be in a
different patchset.
