We have drivers/misc/rp1/ and drivers/misc/lan966x_pci*.c with similar
functionality, so at least there is precedence for putting them here.

>From the old days, we still have drivers/mfd/sm501.c, drivers/mfd/cs5535-mfd.c,
and a few others that open-code the on-chip components as mfd cels
instead of using devicetree description.

At some point, we should think about grouping them into a separate
subdirectory.
