On am33xx we're missing the pmu and emif nodes with their related "ti,hwmods" properties that the SoC interconnect code needs. Note that this will only show up as a bug with "doesn't have mpu register target base" boot errors when the legacy platform data is removed. Let's also update the related binding documentation while at it.
