Particularly discordant in this scheme is the subtle reliance on VFE and VFE Lite declaration ordering in our resources. VFE id is used to determine if a VFE is lite or not and consequently if a VFE requires power-domain attachment. VFE Lite though is not a correct delineation between power-domain and non power-domain state since early SoCs have neither VFE Lite nor power-domains attached to VFEs. Introduce has_pd to the VFE resource structure to allow the CAMSS code to understand if it needs to try to attach a power-domain for a given VFE. As a side-effect from this we no longer need to care about VFE Lite or non-Lite or the id number associated with either and which order the VFE/VFE Lite was declared in. Add the flag and populate the resources. Subsequent patches will disjunct on the bool.
