Subject: [PATCH v2 1/2] bus: brcmstb_gisb: register the fault code hook

Commit 44127b771d9c31 ("bus: add Broadcom GISB bus arbiter timeout/error
handler") added everything that is required to register an ARM fault
handler for imprecise external aborts, except that there is nothing
calling this currently.

We do not need to export that specific function and have to update
arch/arm/mach-bcm/brcmstb.c to call it, simply, register the fault
handler with an arch_initcall.

Signed-off-by: Florian Fainelli <f.fainelli@...il.com>

Changes in v2:
- removed the accidental hunk that added saved_timeout since it does
  not belong in this patch
