dmaengine: dw-edma: Fix unmasking STOP and ABORT interrupts for HDMA

The current logic is enabling both STOP_INT_MASK and ABORT_INT_MASK
bit. This is apparently masking those particular interrupts rather than
unmasking the same. If the interrupts are masked, they would never get
triggered.

So fix the issue by unmasking the STOP and ABORT interrupts properly.
