at_hdmac: Rework suspend_late()/resume_early()
This patch reworks platform driver power management code for at_hdmac from legacy late/early callbacks to dev_pm_ops. The callbacks are converted for CONFIG_SUSPEND like this: suspend_late() -> suspend_noirq() resume_early() -> resume_noirq() Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
