soc/qman: Fix accesses to fqid, cleanup
Preventively mask every access to the 'fqid' h/w field, since it is defined as a 24-bit field, for every h/w descriptor. Add generic accessors for this field to ensure correct access. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: Scott Wood <oss@buserror.net>
