mfd: mfd-core: Remove mfd_clone_cell()
Providing a subsystem-level API helper seems over-kill just to save a
few lines of C-code. Previous commits saw us convert mfd_clone_cell()'s
only user over to use a more traditional style of MFD child-device
registration. Now we can remove the superfluous helper from the MFD API.
