dmaengine: fsl-edma: request per-channel IRQ only when channel is allocated
The edma feature individual IRQs for each DMA channel at some devices.
Given the presence of numerous eDMA instances, each with multiple channels,
IRQ request during probe results in an extensive list at /proc/interrupts.
However, a significant portion of these channels remains unused by the
system.
Request irq only when a DMA client driver requests a DMA channel.
