soc: bcm: brcmstb: biuctrl: Update layout for A72 on 7211
The BIUCTRL layout is a little different on 7211 which is equipped with a Cortex-A72, account for those register offset differences. We will match 7211 specifically in a subsequent commit. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
