[PATCH 6/6] ARM: imx: select ARM_CPU_SUSPEND when necessary

[Arnd Bergmann <arnd@xxxxxxxx>]

On i.MX6, we select ARM_CPU_SUSPEND when building with power management
support, but for some reason this was omitted on i.MX5. Normally we
build kernels for both together so the error only showed up in
randconfig tests.

Without this patch, building imx5 standalone results in:

arch/arm/mach-imx/built-in.o: In function `v7_cpu_resume':
arch/arm/mach-imx/head-v7.S:104: undefined reference to `cpu_resume'
