Fixes for omaps for v4.11-rc cycle:

Browse Source 
- Fix smartreflex platform data regression where I accidentally
   removed legacy platform data still in use
 
 - Fix hypervisor mode for thumb2 kernel
 
 - Fix misplaced tpic2810 to move it to right bus
 
 - Enable INPUT_MOUSEDEV as a loadable module have mice working
 
 - Fix use of gpio-key,wakeup and use wakeup-source instead as
   this accidentally sneaked in during the merge window
 
 - Fix error handling for onenand to properly return error
 
 - Remove legacy gpmc-nand.c that's now dead code, this
   also removes dependency to the MTD tree for further driver
   changes
 
 - Fix device node reference count errors for omap3 and
   related to it also release device nodes after no longer
   needed
