OMAP: control: move plat-omap/control.h to mach-omap2/control.h
Only OMAP2+ platforms have the System Control Module (SCM) IP block. In the past, we've kept the SCM header file in plat-omap. This has led to abuse - device drivers including it; includes being added that create implicit dependencies on OMAP2+ builds; etc. In response, move the SCM headers into mach-omap2/. As part of this, remove the direct SCM access from the OMAP UDC driver. It was clearly broken. The UDC code needs an indepth review for use on OMAP2+ chips.
