arm: bcmbca: add bcm6858 SoC support under CONFIG_ARCH_BCMBCA
BCM6858 is a Broadcom B53 based PON Gateway SoC. It is part of the BCA
(Broadband Carrier Access origin) chipset family. Like other broadband
SoC, this patch adds it under CONFIG_BCM6858 chip config and
CONFIG_ARCH_BCMBCA platform config.
This initial support includes a bare-bone implementation and the
original dts is updated with the one from linux next git repository.
The u-boot image can be loaded from flash or network to the entry point
address in the memory and boot from there to the console.
