mfd: ab8500: Pass AB8500 IRQ to debugfs code by resource
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.
