dmaengine: mxs-dma: fix build failure caused by merge conflicts

In 70f5e23f ("Merge branch 'v5.10/standard/base' into
v5.10/standard/nxp-sdk-5.10/nxp-soc") there was a conflict between
linux-stable backport
1da5d249 ("dmaengine: mxs-dma: Remove the unused .id_table")
and existing nxp SDK commits.

Remove the unnecessary .id_table assignment to fix the following build failure:
| 'mxs_dma_ids' undeclared here (not in a function); did you mean 'mxs_dma_id'?
|   962 |         .id_table       = mxs_dma_ids,
|       |                           ^~~~~~~~~~~
|       |                           mxs_dma_id
