dmaengine: mmp_pdma: Do not warn when IRQ is shared by all chans
When there's a single interrupt for all the DMA channels, the
unsuccessful attempt to request separate IRQs emits useless warnings:
[ 1.370381] mmp-pdma d4000000.dma: IRQ index 1 not found
...
[ 1.412398] mmp-pdma d4000000.dma: IRQ index 15 not found
[ 1.418308] mmp-pdma d4000000.dma: initialized 16 channels
Avoid that, treating the IRQs as optional.
