Fix following sparse warnings:
symbol 'static_irqaction' was not declared. Should it be static?
symbol 'static_irq_count' was not declared. Should it be static?
symbol 'irq_action_lock' was not declared. Should it be static?
symbol 'unexpected_irq' was not declared. Should it be static?
symbol 'handler_irq' was not declared. Should it be static?
returning void-valued expression
returning void-valued expression
returning void-valued expression
symbol 'init_IRQ' was not declared. Should it be static?

Warnings were fixed by addding proper declarations
and fixing return path of a few functions.

There remains several warnings all related to the floppy driver.

bf944c370a sparc: Restore irq_trans_init() call in prom_create_node().
This broke sparc64 in various ways.

Add an empty dummy hook in sparc32's prom_32.c so that we
can potentially handle things on that side similarly, and
in particular avoid a prom_common.c ifdef :-)

7e7e93a228 sparc: Always set AUDIT_ARCH, not just on sparc64.
Without fancy makefile rules it's not straightforward
to prevent both arch/sparc/kernel/audit.o and lib/audit.o
from both being used on sparc32.

Since arch/sparc/kernel/audit.c is identical to lib/audit.c
except some CONFIG_COMPAT protected sections of code, just
use it on sparc32 too as that's the simplest way to fix
this.

5de18cde3b sparc,sparc64: unify prom/
- all files with identical names copied and renamed to *_64.c
- the remaning files copied as is
- added sparc64 specific files to sparc/prom/Makefile
- teach sparc64 Makefile to look into sparc/prom/
- delete unused Makefile from sparc64/prom/

linking order was not kept for sparc64 with this change.
It was not possible to keep linking order for both sparc and sparc64
and as sparc64 see more testing than sparc it was natural to
break linking order on sparc64. Should it have any effect it
would be detected sooner this way.

printf_32.c and printf_64.c are obvious candidates to be merged
but they are not 100% equal so that was left for later

5e53879008 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)
