The cxl create-region documentation describes automatic root decoder
selection when --decoder is omitted, but that behavior has never been
implemented. Users see:
# cxl create-region -m mem0 mem1
cxl region: parse_create_options: no root decoder specified
cxl region: cmd_create_region: created 0 regions
Document --decoder as required.

Automatic root decoder selection may be revisited as part of future
usability enhancements to the cxl create-region command.

interleaved across more than one host-bridge then this value must match

granularity can be specified as long as all devices support that
