[PATCH] ARM: arch.h: Include irq.h

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

Fix the following warning when building imx_v4_v5_defconfig target:

  CC      arch/arm/mach-imx/mach-imx27ipcam.o
In file included from arch/arm/mach-imx/mach-imx27ipcam.c:18:
/home/fabio/linus/linux-2.6/arch/arm/include/asm/mach/arch.h:47: warning: 'struct pt_regs' declared inside parameter list
/home/fabio/linus/linux-2.6/arch/arm/include/asm/mach/arch.h:47: warning: its scope is only this definition or declaration, which is probably not what you want
arch/arm/mach-imx/mach-imx27ipcam.c:78: warning: initialization from incompatible pointer type

'struct pt_regs' is declared in arch/arm/include/asm/irq.h, so include this header.
