[PATCH v3 08/12] dmaengine: fsl-edma: move clearing of register interrupt into setup_irq function

[Frank Li]

This accommodates differences in the register layout of EDMA v3 by moving
the clearing of register interrupts into the platform-specific set_irq
function. This should ensure better compatibility with EDMA v3.
