I've tested and confirmed that it doesn't actually work. We'll need
to sort out how to do this properly later, but for now just remove it
since it also caused build breakage due to using CONFIG_PM_SLEEP
functions without our Kconfig depending on PM_SLEEP.

Still broken upstream.

I saw Eric sending a pull request for it. But it was never pulled, maybe for the subject.
Looks like rc1 will be broken for many arch.

Could be worse. Essentially every allmodconfig/allyesconfig which doesn't configure pm
is affected.

With my tests (v4.4-10282-geae2177):

Build results:
total: 146 pass: 142 fail: 4
Failed builds:

Qemu test results:
total: 96 pass: 94 fail: 2
Failed tests:

arm64 qemu tests are broken for a different reason. There is a patch to fix it,
but for some reason it didn't make it into mainline (yet). It is in -next, though.
