Merge branch 'brcm/stb-smp-uart' into next/drivers

This resolves a nonobvious merge conflict that I got wrong the
first time.

* brcm/stb-smp-uart:
  bus: brcmstb_gisb: save and restore GISB timeout
  bus: brcmstb_gisb: register the fault code hook
  ARM: brcmstb: Kconfig: drop unneeded symbol selections
  ARM: brcmstb: reintroduce SMP support
  ARM: brcmstb: add debug UART for earlyprintk support

Conflicts:
	drivers/bus/brcmstb_gisb.c
