compat: backport run-time power management (5e928f77)

This backports 5e928f77a09a07f9dd595bb8a489965d69a83458

Run-time power management cannot really be backported
given that the implementation added bus specific
callbacks that we won't have on older kernels. If
you really want run-time power management or good
power management upgrade your kernel. We'll just
compile this out as if run-time power management was
disabled just as the kernel disables run-time power
management when CONFIG_PM_RUNTIME is disabled.
