net/qede/base: fix to handle stag update event

Browse Source 
This fix adds a ecore_mcp_update_stag() handler to handle the STAG update
events from management FW and program the STAG value.
It also clears the stag config on PF, when management FW invalidates
the stag value.

Fixes: ec94dbc573 ("qede: add base driver")
Cc: stable@dpdk.org
