The AB8500 external regulator driver is now a device in its own right,
so it requires registering and probing in the normal way. This patch
will ensure the driver is probed once registered for all devices which
support them.

There is no reason for ssbi to have its own top-level driver directory
when the only users of this interface are all MFD drivers. The only
mainline driver using it at the moment (PM8921) is marked broken and in
fact does not compile. I have verified that fixing the trivial build
breakage in pm8921 links in the new ssbi code just fine, but that
can be a separate patch.

The irqdomain core will report a log message for any attempted map call

Versatile irq controller drivers to use -EPERM because it is normal for

Versatile platforms.
