If we get the parent device, regmap handle and interrupt number from mfd

Two way which I can think of here:
Parent device is just dev->parent, you can use dev_get_regmap() to get a
regmap given a struct device and you can use platform resources to pass
the interrupts to the children from the MFD (there's some examples,
wm831x is one).
I think it should work with named regmap. mfd whould init regmap with
name and rtc driver should ask with same name.
I saw three drivers which looks same:
rtc-max77620.c (new from me) and already available rtc-max77686.c,
rtc-max77802.c
Seems I can develop IP based rtc driver as rtc-max77xxx.c
