cxl/region: Handle endpoint decoders in cxl_region_find_decoder()
In preparation for adding a new caller of cxl_region_find_decoders()
teach it to find a decoder from a cxl_endpoint_decoder structure.
Combining switch and endpoint decoder lookup in one function prevents
code duplication in call sites.
Update the existing caller.
