Initializing the MFD child device's fwnode with the parent
or matching ACPI device's fwnode is causing conflict when
software_node (mfd_cell->swnode) is explicitly assigned during
device creation.

Since a device is not expected to have both fwnode and swnode,
this conflict is leading to mfd_add_hotplug_devices() failure.

To fix this issue, skip initializing the fwnode from the parent
or matching ACPI device when a swnode is already present for the
MFD child.
