SSFC: Framework to support two charger sources
Many platforms have requirements to support more than one charge
source (eg. pirika). It can't be supported by just enabling two
different CONFIGS as that can lead to conflicts.
Eg.USD_PD_VBUS_DETECT_TCPC vs USB_PD_VBUS_DETECT_DISCHARGE.
This change provides a framework that supports two different charger
sources in the same build. Please see the CL for relevant logs.
