SoC changes for omaps for v4.3 merge window:

Browse Source 
- Clean-up omap4_local_timer_init to drop deal legacy code
 
 - Provide proper IO map table for dra7
 
 - Clean-up IOMMU layer init code as it now uses IOMMU framework
 
 - A series of changes to fix up dm814x support that's been in a broken
   half-merged state for quite some time
 
 - A series of PRCM and hwmod changes via Paul Walmsley <paul@pwsan.com>:
 
   - I/O wakeup support for AM43xx
   - register lock and unlock support to the hwmod code (needed for the RTC
     IP blocks on some chips)
   - several fixes for sparse warnings and an unnecessary null pointer test
   - a DRA7xx clockdomain configuration workaround, to deal with some hardware
     bugs
