riscv: dts: spacemit: Use symbolic PDMA request numbers on K1

Browse source

The PDMA request numbers (DRQ) are fixed values specific to the SoC from
a hardware perspective. The detailed definition can be found in K1 User
Manual [1], Chapter 9.4.3 DMA Connectivity & Assignments. Add a DTS
header file to define the symbolic names for the DRQs of non-secure DMA
peripherals.

Convert the K1 SPI3 node to these macros.
