[RFC PATCH 04/11] OMAP: Add early device for system control module

[Eduardo Valentin <eduardo.valentin@xxxxxx>]

This is a way to add an early device for system control module.
the code is also requesting for driver registration and probing.
Done at early_initcall because at that time, ioremapping is possible.
