[PATCH v2] dmaengine: dw-edma: Remove dw_edma_add_irq_mask()

[Devendra K Verma]

From: Devendra K Verma <devendra.verma@amd.com>

Function dw_edma_add_irq_mask() sets the mask of the
interrupts alloted to read / write channels in a variable.
The mask set for read / write channels is niether used nor
this function is called else where, making it redundant.
The redundant function can be removed safely as it is
not affecting anything.
