Merge branch 'bcmring/removal' into next/cleanup2

From "Christian Daudt" <csd@broadcom.com>:

Remove mach-bcmring as this is no longer maintained or used.

Updated the removal with:
 - drop the edit to mach-types requested by Russell King
 - eliminate defconfig mod from patch 1 requested Olof Johansson

Also switched to using git send-email to avoid word-wrapping
problems

* bcmring/removal:
  ARM: Remove mach-bcmring
