[PATCH v2 06/19] dmaengine: dw-edma: Move callback result helper before LL helpers

[Koichiro Den]

From: Frank Li <Frank.Li@xxxxxxx>

Move dw_hdma_set_callback_result() next to the descriptor helpers so
linked-list completion and reset code can use it without a forward
declaration.

No functional change.

Based on Frank's original submission:
https://lore.kernel.org/dmaengine/20260109-edma_dymatic-v1-2-9a98c9c98536@xxxxxxx/

Changes in v2:
  - Move the helper before the LL helpers so later patches do not need
    another relocation.
