[PATCH] ARM: mach-imx: cpu: Include <linux/err.h>

Commit e709f38cd7 (ARM: imx6: report soc info via soc device) causes the 
following build error on imx_v4_v5_defconfig:

arch/arm/mach-imx/cpu.c: In function 'imx_soc_device_init':
arch/arm/mach-imx/cpu.c:129:2: error: implicit declaration of function 'IS_ERR' [-Werror=implicit-function-declaration]

Include <linux/err.h> to fix it.
