soc: brcmstb: Split initialization
We may need access to family_id and product_id fairly early on boot for other parts of the code (e.g: biuctrl.c), so split the initialization between an early_init() and an arch_initcall() which allows us to do that. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
