octeontx2-af: Promisc enable/disable through mbox

Browse Source 
[ Upstream commit af42088bdaf292060b8d8a00d8644ca7b2b3f2d1 ]

In legacy silicon, promiscuous mode is only modified
through CGX mbox messages. In CN10KB silicon, it is modified
from CGX mbox and NIX. This breaks legacy application
behaviour. Fix this by removing call from NIX.
