ARM: SoC specific updates 

These changes are all specific to an soc family or the code for
 one soc. Lots of work for Tegra3 this time, but also a lot of other
 platforms. There will be another (smaller) set of soc patches later in
 the merge window for stuff that has dependencies on external trees or
 that was sent just before the merge window opened.
 
 The asoc tree added a few devices to the i.mx platform, which conflict
 with other devices added in the same place here.
 
 The tegra Makefile conflicts between a number of branches, mostly because
 of changes regarding localtimer.c, which was removed in the end.
