Named power domains remove magic index dependencies. Similarly adding an "is_lite" flag to our resources removes the last of the magic indexing sins, so this is an opportune series to add it in.

As I rebased this series I realised we had some magic indexing for VFE v VFE Lite, which isn't the root cause of my bug bear in this series but is the same sin - inferring functionality from indexing. Once we transition fully to named pds we won't need a 'has_pd' to flag which VFEs need power-domain attachment and which don't. That transition will require populating all upstream dtsi with pd-names and then deprecating the old way. has_pd is a far better choice than inferring from indexes so, I've added. Link: https://git.codelinaro.org/bryan.odonoghue/kernel/-/commits/aa45a2b58aa1e187a2698a65164d694251f08fa1 V1: At the moment the Qcom CAMSS driver relies on the declaration order of power-domains within the dtsi to determine which power-domain relates to a VFE and which power-domain relates to the top-level (top) CAMSS power-domain. VFE power-domains must be declared prior to the top power-domain. The top power-domain must be declared last. Early SoCs have just one top power-domain with later SoCs introducing VFE specific power-domains. Differentiating between the number of power-domains results in lots of code which is brittle and which we can mostly get rid of with named power-domains. The reliance on declaration ordering is in-effect magic number indexing. This series introduces named power-domains for CAMSS and refactors some of the code in CAMSS to support the new named power-domains. We continue to support the legacy indexing model with an intention to remove after a reasonable transition period. New SoC additions should use named power-domains from now on.
