ARM: bcm2835: convert to multi-platform
This allows BCM2835 be included in a kernel build that supports multiple
SoCs at once, which is useful for distro kernels.
This change:
* Moves bcm2835's debug-macro.S into ARM's include/debug/, and hooks it
into the relevant menu.
* Moves bcm2835's Kconfig into its own directory, as seems typical for
multi-platform conversions.
* Removes bcm2835_soc.h, and moves the content to the files where it was
used; just one usage per define.
* Deletes some headers and Makefile.boot that aren't needed now that we
support multi-platform.
