soc: brcmstb: biuctrl updates for 64-bit chips

Hi all,

This patch series updates the Broadcom STB Bus Interface Unit controller to support newer chips such as 7260, 7268, 7271 and 7278. These chips require additional tuning in order to provide the expected bus throughput.

In the process, we need to re-organize the common.c file a little bit in order to extract the family and product identifiers a little earlier.

Finally, by moving the biuctrl initialization an early_initcall level, we can remove some code from the ARM-32bit machine descriptor file.

Provided that we are happy with these changes, I would route them through my drivers/next branch and a subsequent Broadcom ARM SoC pull request.

Thank you

Changes in v2:

- collect Rob's acked-by on the first patch
- fixed the binding as suggested by Rob
