After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.
Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/scsi/ and in include/scsi/scsi_device.h.

Note: This depends on commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if
PM_SLEEP is selected) which is only in linux-next at the moment (via the
linux-pm tree).
Please let me know if it is OK to take this one into linux-pm.

Just one nitpeak: since scsi_pm.o is only compiled when CONFIG_PM is
set, I think we can skip the #ifdef CONFIG_PM ... #endif macro in this
file now. I mean something like this:
Ah, right, I overlooked that, thanks!
I've folded the below into the SCSI patch.
