[PATCH 5/8] OMAP2+: hwmod: allow multiple calls to omap_hwmod_init()

There's no longer any reason why we should prevent multiple
calls to omap_hwmod_init(). It is now simply used to register an
array of hwmods.
This should allow a subset of hwmods (e.g., hwmods
handling the system clocksource and clockevents) to be registered
earlier than the remaining mass of hwmods.
