This patch week depend on the below serise.
https://lore.kernel.org/imx/20251208-dma_prep_config-v1-0-53490c5e1e2a@nxp.com/

Basic change

struct dw_edma_desc *desc
       └─ chunk list
            └─ burst list

To

struct dw_edma_desc *desc
            └─ burst[n]

And reduce at least 2 times kzalloc() for each dma descriptor create.

I only test eDMA part, not hardware test hdma part.

The finial goal is dymatic add DMA request when DMA running. So needn't
wait for irq for fetch next round DMA request.

This work is neccesary to for dymatic DMA request appending.

The post this part first to review and test firstly during working dymatic
DMA part.
