ARM: OMAP2+: common: remove mach-omap2/common.c globals and map_common_io code

Browse source 
Get rid of the mach-omap2/common.c globals by moving the global
initialization for IP block addresses that must occur early into
mach-omap2/io.c.  In the process, remove the *_map_common_io*() and
SoC-specific *set_globals* functions.
