Call brcmstb_biuctrl_init() in brcmstb's init_irq machine descriptor
callback since we need to setup the Bus Interface Unit before SMP in
particular, but we also need to be able to remap registers.

I believe you're introducing a dependency on CONFIG_SOC_BRCMSTB, but
it's not represented in Kconfig. Maybe SOC_BRCMSTB shouldn't be
user-selectable, and it should just be select-ed by ARCH_BRCMSTB?
