board-inspector: replace enter_scope with change_scope

The method `enter_scope` of class `Context` is a reduced implementation of
`change_scope` which assumes that the given name is simply a NameSeg. This
method is currently only used when a new named scope is opened by a
DefDevice object for historical reasons.

As the other named-scope-opening objects all use `change_scope` which can
handle arbitrary NameString, this patch unifies the code by removing
`enter_scope` and replacing the only occurrence with `change_scope`. This
also resolves the parsing of AML templates in board XMLs where device names
can be more than a simple NameSeg.
