Subject: [PATCH v2 5/5] net: marvell: prestera: unbind sfp port on exit

From: Elad Nachman <enachman@...vell.com>

Call unbinding of the sfp port when ports are released, This will call
phylink_destroy() to cleanup and destroy the phylink instance, needed
to unregister SFP and free used memory, which will otherwise leak.

Reported-by: Köry Maincent <kory.maincent@...tlin.com>
Closes: https://lore.kernel.org/lkml/20240312164526.4a0e242a@kmaincent-XPS-13-7390/
Fixes: 501ef3066c89 ("net: marvell: prestera: Add driver for Prestera family ASIC devices")
