sparc,sparc64: unify Makefile
To unify Makefile for sparc and sparc64 a few other steps was needed:
1) separate defconfig files for sparc and sparc64 is required,
so locate these in arch/sparc/configs
2) removoval of hack in toplevel Makefile to deal with that
headers was in a separate directory compared to the rest
The unification of the Makefile required usage of several
foo-$(CONFIG_SPARCnn) +=
due to a few directories pending unification.
This will be cleaned up when we unify the remaining directories.
Included in this patch are the deletion of a few files in
sparc64 as they are no longer needed: Makefile + Kconfig.
arch/sparc64/ will after this patch is applied only
have four directories (prom, lib, kernel, boot)
