dt-bindings: dmaengine: Add SpacemiT K3 DMA compatible string

Browse Source 
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.
