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.
