dmaengine: tegra210-adma: update system sleep callbacks

Browse source

If the driver is active till late suspend, where runtime PM cannot run,
force suspend is essential in such case to put the device in low power
state. Thus pm_runtime_force_suspend and pm_runtime_force_resume are
used as system sleep callbacks during system wide PM transitions.
Late system sleep callbacks are used to ensure, for instance, that the
sound core has suspended any on-going activity, including stopping the
ADMA if active, before we attempt to suspend the ADMA.
