Subject: [PATCH 0/1] Renaming AMBA to PRIMECELL

The only patch in this series renames CONFIG_ARM_AMBA to
CONFIG_ARM_PRIMECELL in Kconfig and the only source file with
#ifdef.

I compile-tested on the following defconfigs: "integrator realview
versatile vexpress bcmring ep93xx lpc32xx u300 u8500 nhk8815 spear3xx
spear6xx", diffing the stderr of the two compilations.

While this patch is self-contained and works, there are other
open points. I think only 4- below is worth doing, but I need
confirmation before doing that.

1- drivers/of/platform.c still has "amba" in its names. Worse, it has
"amba-bus" in its device tree compatibility list (and some drivers
have it too). I think this should stay.

2- Actually, grepping for "amba" or "AMBA" finds a lot of related
code. Some uses are correct and some are not.  I don't think an
audit here is worth the effort; users will adapt over time, only
where it makes sense and only when otherwise touching the code.

3- Should drivers/amba/bus.c  be renamed to drivers/primecell/bus.c
or drivers/amba/primecell.c (I think the former but I'm not sure
it's the bext name anyways)

4- Should linux/amba/bus.h be renamed to linux/primecell/bus.h or
linux/amba/primecell.h? (I think the former, leaving the old
name around for a while, so out-of-tree drivers are happy
and #warn'ed about the change.
