Subject: [PATCH 2/6] remoteproc: imx_rproc: Move imx_rproc_dcfg closer to
 imx_rproc_of_match

Move the imx_rproc_dcfg structure definitions closer to imx_rproc_of_match
to prepare for adding start/stop/detect_mode ops for each i.MX variant.

This relocation avoids the need to declare function prototypes such as
'static int imx_rproc_xtr_mbox_init(struct rproc *rproc, bool tx_block)'
at the beginning of the file, improving code organization and readability.

No functional changes.
