mfd: mfd-core: Ensure disabled devices are ignored without error
Commit e49aa9a9bd22 ("mfd: core: Make a best effort attempt to match
devices with the correct of_nodes") changed the semantics for disabled
devices in mfd_add_device(). Instead of silently ignoring a disabled
child device, an error was returned. On receipt of the error
mfd_add_devices() the precedes to remove *all* child devices and
returns an all-failed error to the caller, which will inevitably fail
the parent device as well.
This patch reverts back to the old semantics and ignores child devices
which are disabled in Device Tree.
