We register the ab8500 as an MFD device from db8500 code during Device Tree
boot in order to solve some limitations of DT. However, when Device Tree is
not enabled, we still want to allow platform code to register the ab8500 in
the normal way. Here we force MFD device registration of the ab8500 only
when booting with Device Tree enabled.

Solves this issue:
WARNING: at fs/sysfs/dir.c:526 sysfs_add_one+0x88/0xb0()
sysfs: cannot create duplicate filename '/bus/platform/devices/ab8500-core.0'

Does the following patch fix your issue?

No, it's unrelated.
