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.
