[PATCH] ARM: mxc: add missing include

[Robert Schwebel]

Without this include, we get the following error when building
imx_v4_v5_defconfig:

In file included from arch/arm/plat-mxc/include/mach/iomux-mx27.h:23:0,
                 from arch/arm/mach-imx/mach-imx27ipcam.c:22:
arch/arm/plat-mxc/include/mach/iomux-v1.h:99:19: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'imx_iomuxv1_init'
