Mrinmay Sarkar 9f646ff25c dmaengine: dw-edma: Do not enable watermark interrupts for HDMA
DW_HDMA_V0_LIE and DW_HDMA_V0_RIE are initialized as BIT(3) and BIT(4)
respectively in dw_hdma_control enum. But as per HDMA register these
bits are corresponds to LWIE and RWIE bit i.e local watermark interrupt
enable and remote watermarek interrupt enable. In linked list mode LWIE
and RWIE bits only enable the local and remote watermark interrupt.

Since the watermark interrupts are not used but enabled, this leads to
spurious interrupts getting generated. So remove the code that enables
them to avoid generating spurious watermark interrupts.

And also rename DW_HDMA_V0_LIE to DW_HDMA_V0_LWIE and DW_HDMA_V0_RIE to
DW_HDMA_V0_RWIE as there is no LIE and RIE bits in HDMA and those bits
are corresponds to LWIE and RWIE bits.
