cxl/region: Move region-position validation to a helper
In preparation for region autodiscovery, that needs all devices
discovered before their relative position in the region can be
determined, consolidate all position dependent validation in a helper.
Recall that in the on-demand region creation flow the end-user picks the
position of a given endpoint decoder in a region. In the autodiscovery
case the position of an endpoint decoder can only be determined after
all other endpoint decoders that claim to decode the region's address
range have been enumerated and attached. So, in the autodiscovery case
endpoint decoders may be attached before their relative position is
known. Once all decoders arrive, then positions can be determined and
validated with cxl_region_validate_position() the same as user initiated
on-demand creation.
