The DMA request mappings are hardware-hardwired and differ between the K1 and K3 SoCs.
Therefore, separate header files are required to define these unique constants for each
platform to ensure correct DMA channel allocation in the device tree.

Aside from this K1-related patch, the rest of the series focuses on adding support for
the K3 SoC. I included the K1 header because I noticed it was missing in the upstream
tree while working on the K3 support.

It seems my attempt to 'clean up' K1 while adding K3 has caused unnecessary confusion.
Would you prefer me to remove the K1 patch from this series and submit it as a separate
patch?
