[PATCH 2/2] riscv: dts: spacemit: Use symbolic PDMA request numbers on K1

[Guodong Xu <docular.xu@gmail.com>]

The K1 SPI3 node's "dmas" property hard-codes its PDMA request numbers.
Include <dt-bindings/dma/spacemit,k1-pdma.h> and use the K1_PDMA_SPI3_RX/TX
macros instead, for better code readability and easy for future
maintenance.

No functional change.
