ARM: 8099/1: EXYNOS: Fix MCPM build with SUSPEND=n
Building of EXYNOS5420_MCPM with disabled SUSPEND fails:
arch/arm/mach-exynos/built-in.o: In function `exynos_mcpm_init':
arch/arm/mach-exynos/mcpm-exynos.c:361: undefined reference to `mcpm_loopback'
The exynos_mcpm_init() in mcp-exynos.c calls mcpm_loopback() which
depends on cpu_suspend function (ARM_CPU_SUSPEND).

This is needed to provide CPU and cluster power management
on Exynos5420 implementing big.LITTLE.
