[U-Boot] [PATCH] arm: imx: imx-common: init: move arch init common setup

[Peng Fan]

Hi Adrian,

Since this is only for mx6, why move the code to imx-common?
"
> ifeq ($(SOC),$(filter $(SOC),mx6))
>-obj-y 	+= cache.o
>+obj-y 	+= cache.o init.o
"

Also many pieces of code are only for imx6, imx7 do not need them for now, such as
the ldo ramp part.

I think basic imx7 support do not need such a big change, if we do need to
consolidate code for common usage, we can do this when we need to add more
stuff.

Regards,
Peng.
