Subject: [PATCH] dma: ste_dma40: fix up static memcpy event lines

From: Linus Walleij <[email protected]>

The commit
"dmaengine: ste_dma40: Assign memcpy channels in the driver"
had two problems:
- It assigned magic numbers to the memcpy event lines
instead of giving them symbolic names.
- It seems to have missed one of the memcpy event lines,
number 51.

This patch fixes it up.
