Russell King dc6946cbef thermal: armada: fix legacy resource fixup
When the armada thermal module is inserted, removed and then reinserted,
the system panics as per the messages below.  The reason is that "edit"
a live resource in the resource tree twice, and end up with it pointing
to some other hardware.

Editing live resources (resources that are part of the registered
resource tree) is not permissible - the resource tree is an ordered
set of resources, sorted by start address, and when a new resource is
inserted, it is validated that it (a) fits within its parent resource
and (b) does not overlap a neighbouring resource.

Get rid of this resource editing.  We can instead adjust the return
value from ioremap() as ioremap() deals with the creation of page-
based mappings - provided the adjustment does not cross a page
boundary.
