ARM: SoC fixes 

Here's the first batch of fixes for this release cycle.
 
 Main diffstat here is the re-deletion of netx. I messed up and most
 likely didn't remove the files from the index when I test-merged this
 and saw conflicts, and from there on out 'git rerere' remembered the
 mistake and I missed checking it. Here it's done again as expected.
 
 Besides that:
 
  - A defconfig refresh + enabling of new drivers for u8500
 
  - i.MX fixlets for i2c/SAI/pinmux
 
  - sleep.S build fix for Davinci
 
  - Broadcom devicetree build/warning fix
