cxl/region: Delete 'region' attribute from root decoders
For switch and endpoint decoders the relationship of decoders to regions
is 1:1. However, for root decoders the relationship is 1:N. Also,
regions are already children of root decoders, so the 1:N relationship
is observed by walking the following glob:
/sys/bus/cxl/devices/$decoder/region*
Hide the vestigial 'region' attribute for root decoders.
