From: Magnus Damm <damm@xxxxxxxxxx>
This patch reworks platform driver power management code
for txx9dmac 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: Magnus Damm <damm@xxxxxxxxxx>

Untested but compiles fine.
