This commit defines `struct mfd_cell` and adds two function stubs. The function stubs are not implemented but still return success. They log a message to indicate they need to be implemented. Also, unlike Linux, <linux/mfd/core.h> includes <linux/ioport.h>. This works around the fact that we can't include <linux/ioport.h> from <linux/pci.h>, due to a conflict with the FreeBSD-native `struct resource`. The amdgpu DRM driver started to use it in Linux 6.11. Reviewed by: bz, emaste Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D55736
