arm64: psci: Fix build breakage without PM_SLEEP

Browse Source 
Fix build failure of defconfig when PM_SLEEP is disabled (e.g. by
disabling SUSPEND) and CPU_IDLE enabled:

arch/arm64/kernel/psci.c:543:2: error: unknown field ‘cpu_suspend’ specified in initializer
  .cpu_suspend = cpu_psci_cpu_suspend,
  ^
arch/arm64/kernel/psci.c:543:2: warning: initialization from incompatible pointer type [enabled by default]
arch/arm64/kernel/psci.c:543:2: warning: (near initialization for ‘cpu_psci_ops.cpu_prepare’) [enabled by default]
make[1]: *** [arch/arm64/kernel/psci.o] Error 1

The cpu_operations.cpu_suspend field exists only if ARM64_CPU_SUSPEND is
defined, not CPU_IDLE.
