[Thomas Abraham]

For s3c64xx and exynos platforms, make the selection of PM_GENERIC_DOMAINS
depend on the CONFIG_PM.

What's the underlying issue here?  This seems like something the PM core
should be dealing with gracefully...

The PM_GENERIC_DOMAINS config option has dependency on CONFIG_PM
option. When building with PM disabled, the following errors occur.

warning: (PLAT_S3C64XX && CPU_EXYNOS4210) selects PM_GENERIC_DOMAINS
which has unmet direct dependencies (PM)

Right, this does seem like something which it'd be better to handle
more gracefully in the PM core.

Ok. Selecting PM_GENERIC_DOMAINS without checking for dependency on PM
did not seem correct.

I dunno, perhaps the PM guys will disagree but it seems like if the
idiomatic way to use this is to select it the API ought to cope with
being selected when half enabled.

As I've said before I'm in favour of just making CONFIG_PM non-optional,
I'm not convinced there's much meaningful use case for disabling it.
