eDMA Clear Interrupt Request Register (EDMA_CINT)

The EDMA_CINT provides a simple, memory-mapped mechanism to clear a given bit in the EDMA_INT
to disable the interrupt request for a given channel. The given value on a register write causes the
corresponding bit in the EDMA_INT to be cleared. Setting the CAIR bit provides a global clear function,
forcing the entire contents of the EDMA_INT to be cleared, disabling all DMA interrupt requests. Reads
of this register return all zeroes.
