One patch is supposed to modify/add one thing at a time in the kernel. Separating platform specific code from imx-drm/imx-hdmi is one thing. Adding support for multi-byte register access is something different. i.e. Something like. 1/3 split platform specific code out. 2/3 move/rename imx-hdmi outside the folder 3/3 add support for multi byte register width access. If there are other things that are not directly relevant to the patch, it goes in a different patch. Bug fixes are also separate. This should result in readable patches that can be reviewed easily. The maintainers might be able to guide on how to further split the patches if necessary.
