dmaengine: shdma: SH_DMAC_MAX_CHANNELS message fix
Fix the recently added SH_DMAC_MAX_CHANNELS handling code in

dmaengine: shdma: Fix SH_DMAC_MAX_CHANNELS handling
Without this fix the shdma driver outputs silly messages in
case SH_DMAC_MAX_CHANNELS happens to match the platform data:
sh-dma-engine sh-dma-engine.0: Attempting to register 20 DMA channels when a max
imum of 20 are supported.
