[PATCH] ARM: PM: build sleep/suspend code for idle path also (not only suspend)

Some platforms (e.g. OMAP) use the same common cpu_suspend/cpu_resume
helpers during idle as well as suspend.

Currently, if suspend is disabled (CONFIG_PM_SLEEP=n) and the platform
idle code is using the common cpu_suspend/cpu_resume functions, the
kernel will not link.

Since platform code commonly uses CONFIG_PM=y to build it's idle code,
build the common sleep/suspend code based on CONFIG_PM instead of
CONFIG_PM_SLEEP.

Applies on Russell's devel-stable branch, where the new common
suspend/resume code is queued.

    ARM: pm: let platforms select cpu_suspend support

    Support for the cpu_suspend functions is only built-in
    when CONFIG_PM_SLEEP is enabled, but omap3/4, exynos4
    and pxa always call cpu_suspend when CONFIG_PM is enabled.
