ARM: SoC cleanups for v4.2

Browse source 
A relatively small setup of cleanups this time around, and similar to last time
 the bulk of it is removal of legacy board support:
 
 - OMAP: removal of legacy (non-DT) booting for several platforms
 - i.MX: remove some legacy board files
 
 Conflicts: None
