Fix several bugs in the omap-dma driver's probe error and remove paths:
missing return after failure, CPU PM notifier leaks and missing RCU
synchronization, channels freed without stopping hardware, IRQs left
enabled during teardown, descriptor pool destroyed too early, wrong
interrupt register used in remove, and a flexible array conversion.

v3: Address remaining review comments:
  - Split CPU PM notifier fix into leak fix + RCU sync
  - Add missing return in probe error path
  - Guard IRQENABLE_L1 accesses for legacy platforms
v2: Fix sashiko comments and add extra patch
