[PATCH 03/07] dma: rework txx9dmac suspend_late()/resume_early()

[Magnus Damm <magnus.damm-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Magnus Damm <damm-AlSX/UN32fvPDbFq/vQRIQ@public.gmane.org>

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-AlSX/UN32fvPDbFq/vQRIQ@public.gmane.org>

 Untested but compiles fine.
