ARM: mm: Fix ifdef around cpu_*_do_[suspend, resume] ops

Ifdef around cpu_\name\()_do_suspend and cpu_\name\()_do_resume
ops in proc-macros.S should check for CONFIG_ARM_CPU_SUSPEND and
not CONFIG_PM_SLEEP.  Fix it.

[ Please note that cpu_v7_do_[suspend,resume] code in proc-v7.S
  already correctly checks for CONFIG_ARM_CPU_SUSPEND, same is
  true for functions for other architectures. ]

This fix is needed for decoupling suspend/resume and advanced
cpuidle support on Exynos platform (next patch fixes build for
config with CONFIG_PM_SLEEP=n and CONFIG_ARM_EXYNOS_CPUIDLE=y).

If this fix is not present then the following OOPS happens on
the first attempt to go into advanced cpuidle mode (AFTR):
