In effect this hard-codes VFE indexes to power-domain indexes in the dtsi and mandates a very particular ordering of power domains in the dtsi, which bears no relationship to a real hardware dependency. As a first step to rationalising the VFE power-domain code and breaking the magic indexing in dtsi use per-VFE pointers to genpd linkages. The top-level index in msm_vfe_subdev_init is still used to attain the initial so no functional or logical change arises from this change.
