[GIT PULL] ARM: brcmstb: SMP, Kconfig, earlyprintk and GISB fixes

[Florian Fainelli]

These changes were posted late during the v3.18 release cycle, and were
eventually added to your 'late' branch, but here is an updated version

Thanks!

  bus: brcmstb_gisb: save and restore GISB timeout (2014-10-20 12:44:42 -0700)

----------------------------------------------------------------
This pull request contains 3 changes for the brcmstb platform and 2 changes
to the GISB bus arbiter driver

- fist patch adds earlyprintk to brcmstb platforms using the existing 8250
  infrastructure

- second patch re-introduces SMP support after fixing the problems we had in
  the initial implementation, for this patch to apply cleanly, I had to advance
  up to "ARM: brcmstb: revert SMP support"

- third patch is dropping unused Kconfig dependencies

- fourth patch registers the ARM fault code for external aborts that the GISB
  bus arbiter driver is designed to assit

- fifth patch does save/restore the GISB arbiter timeout across S3
  suspend/resume cycles

Thanks!
