soc: fsl: qbman: Add CGR update function
[ Upstream commit 914f8b228ede709274b8c80514b352248ec9da00 ]
This adds a function to update a CGR with new parameters. qman_create_cgr
can almost be used for this (with flags=0), but it's not suitable because
it also registers the callback function. The _safe variant was modeled off
of qman_cgr_delete_safe. However, we handle multiple arguments and a return
value.
