It is overkill to rename the entirety of ahci_platform just for one override function.
This sort of thing I would have expected to be added directly to ahci_platform.c.

It might be overkill for only one controller. but it is more clean and readable to have different SoC specific changes in separate files, especially when more SoCs need to make similar changes.

I think that renaming the file is not necessary. You can just rename the module in the makefile.

Personally I like the current approach more than putting controller-specific fixups directly into ahci_platform.

My main objection is the renaming. If ahci_platform wants to export some symbols for SoC modules like ahci_platform_cns, that's ok.

In general, follow the library approach rather than linking modules together in strange ways.
