dmaengine: dw-edma: Fix wrong interrupt bit set for HDMA
[ Upstream commit 7b52ba8616e978bf4f38f207f11a8176517244d0 ]
Instead of setting HDMA_V0_LOCAL_ABORT_INT_EN bit, HDMA_V0_LOCAL_STOP_INT_EN
bit got set twice, due to which the abort interrupt is not getting generated for
HDMA. Fix it by setting the correct interrupt enable bit.
