The only mach/irqs.h user outside arch/arm/mach-imx is sound/soc/fsl/imx-pcm-fiq.c, which refers to mxc_set_irq_fiq(). Though moving the declaration into imx-pcm-fiq.c will result in the checkpatch below, let's do it to gain the multi-platform support for mach-imx.
WARNING: externs should be avoided in .c files
Inside arch/arm/mach-imx, the only users to mach/irqs.h are avic.c and tzic.c for referring to macro FIQ_START. Let's move the macro into irq-common.h and get rid of mach/irqs.h completely.
