We need some sort of kconfig option to differentiate NS2 clock driver
from being pulled in all the time.

The Broadcom Northstar 2 SoC is architected under the iProc

NS2 code is dragged in for all IPROC SoCs. We need a config option for
NS2 (CONFIG_ARCH_BCM_NS2) to avoid this (if Arnd allows this for ARMv8
processors... ?).
You can see below ARMv7 processors don't have this problem.
If not we need to add CONFIG_CLK_NS2.
