mfd_add_devices() is "const" again. Hence make all cell data passed to

However, when we are registering devices using internal systems such as MFD or platform registration, we can use such terminology. In this case we can and should use the platform device ID mechanism to specify which device we wish to utilise by detailing pinctrl-<device_name>.

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.
