remove software_suspend()
Remove software_suspend() and all its users since pm_suspend(PM_SUSPEND_DISK) should be equivalent and there's no point in having two interfaces for the same thing. The patch also changes the valid_state function to return 0 (false) for PM_SUSPEND_DISK when SOFTWARE_SUSPEND is not configured instead of accepting it and having the whole thing fail later.
