memregion: Drop unused IORES_DESC_* parameter from cpu_cache_invalidate_memregion()
The res_desc parameter was originally introduced for documentation purposes
and with the idea that with HDM-DB CXL invalidation could be triggered from
the device. That has not come to pass and the continued existence of the
option is confusing when we add a range in the following patch which might
not be a strict subset of the res_desc. So avoid that confusion by dropping
the parameter.
