Subject: [PATCH 2/9] dmaengine: dw-edma: Typos fixes

From: Kory Maincent <[email protected]>

Fix "HDMA_V0_REMOTEL_STOP_INT_EN" typo error.
Fix "HDMA_V0_LOCAL_STOP_INT_EN" to "HDMA_V0_LOCAL_ABORT_INT_EN" as the STOP
bit is already set in the same line.

Signed-off-by: Kory Maincent <[email protected]>
Fixes: e74c39573d35 ("dmaengine: dw-edma: Add support for native HDMA")
---

This patch is fixing a commit which is only in dmaengine tree and not
merged mainline.
