The AB8500 debug code which was merged in parallell with the
multiplatform work incidentally introduced a new instance using
the <mach/irqs.h> header which is now deleted, causing this
build regression:

drivers/mfd/ab8500-debugfs.c:95:23:
fatal error: mach/irqs.h: No such file or directory
compilation terminated.
make[4]: *** [drivers/mfd/ab8500-debugfs.o] Error 1

The code most certainly never worked with device tree either
since that does not rely on this kind of hard-coded interrupt
numbers.

Fix the problem at the root by passing it as a named resource
from the ab8500-core driver. Use an untyped resource to
stop the MFD core from remapping this IRQ relative to the
AB8500 irqdomain.

As I am working on SPARSE_IRQ a number of implicit resource
grabs in the kernel become evident. For example, some includes
like <linux/irqs.h> would implicitly include <mach/irqs.h>
and then from there <mach/db8500-regs.h>.

In many cases it is masking the fact that drivers do not
properly use resources to pass their dependencies, base
addresses etc. So write explicit #include statements with
TODO items to have this fixed the proper way to all drivers
doing this.
