Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC multiplatform code changes from Olof Johansson:
 "The changes here belong to two main platforms:

   - Atmel At91 is flipping the bit and going multiplatform.  This
     includes some cleanups and removal of code, and the final flip of
     config dependencies

   - Shmobile has several platforms that are going multiplatform, but
     this branch also contains a bunch of cleanups that they weren't
     able to keep separate in a good way.  THere's also a removal of one
     of their SoCs and the corresponding boards (sh7372 and mackerel)"
