DMA: Rework txx9dmac suspend_late()/resume_early() 



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()
