AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce
SoC specific hook with a call to OMAP2+ generic lateinit hook. This
allows the generic late initializations such as cpufreq hooks to be
active.
Based on out-of-tree patches that need to be introduced in
mainline, this introduction allows us to provide the foundation for
further SoC specific features as they are developed.
