I would go further and spell it as platform.c.

This seems incorrect.

Perhaps you may use the opportunity to spell codenames in a better way, i.e.
Sunrise Point
Cannon Lake
Ice Lake
Tiger Lake

as it's done almost everywhere else in the kernel.

objs suffix is not for kernel modules.
Moreover, := has a difference to +=. Why is the latter in use?

This will have the very same issue as with the core module. On top of
that, do you need a separate module for it? If so, why?
