dt-bindings: dmaengine: Add SpacemiT K3 DMA compatible string
Add the "spacemit,k3-pdma" compatible string for the SpacemiT K3 SoC. While the K3 PDMA IP reuses most of the design found on the earlier K1 SoC, a new compatible string is required because the DRCMR (DMA Request/Command Register) base address for extended DMA request numbers (>= 64) differs from the K1 implementation.
