Bryan O'Donoghue ac6494e0ca media: qcom: camss: Flag which VFEs require a power-domain
At the moment we have some complex code for determining if a VFE requires a
power-domain attachment. 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.
