It bisects down to the following commit, but reverting it doesn't
solve the problem. I haven't looked deeper, but I expect that further
patches have done something similar of pulling in IRQ_DOMAIN, quite
possibly other MFD drivers, but not necessarily.

    mfd: cros_ec: Add MFD_CORE dependency

    CONFIG_MFD_CROS_EC requires CONFIG_MFD_CORE for a couple of functions that
    are declared but not defined:

        ERROR: "mfd_remove_devices" [drivers/mfd/cros_ec.ko] undefined!
        ERROR: "mfd_add_devices" [drivers/mfd/cros_ec.ko] undefined!

    Fix it by selecting CONFIG_MFD_CORE anytime CONFIG_MFD_CROS_EC is enabled.
