Broadcom STB SoCs (brcmstb) require an early setup of their Bus Interface Unit control register, this needs to happen before SMP is brought up because it affects how the CPU complex will be interfaced to the memory controller. Add support code which properly initializes the BIU registers based on whether "brcm,write-pairing" is present in Device Tree, and take care of saving and restoring credit register settings during system-wide suspend/resume operations.
