[PATCH] net: tsec: mark tsec_set_promisc() as __maybe_unused

Since the tsec driver supports both configurations with and without
DM_ETH, and since the eth_ops :: set_promisc() method is only provided
for DM_ETH, the implication is that builds with DM_ETH disabled will
result in a 'defined but not used' warning.

To silence those, mark the function as __maybe_unused.
