[sw] Add dif_pwrmgr_smoktest
- The test puts the device to sleep and immediately wakes up via usb
- The usb wakeup is FAKE, the usb device is not actually enumerated. Instead the usbdev presents to be in suspend to activate the wake logic, which is then used to trigger a wakeup.

[dv] Convert existing dif_pwrmgr_smoketest into a dv only test
- The test relies on specific dv behvaior that cannot always be replicated in other systems without intervention.

[sw] update dif_pwrmgr_smoketest
- use aon_timer for wakeup instead of usb
- this should now be portable across all targets
