generic: remove patch to fix vlan setup on mv88e6xxx

This patch was present in Linux kernel [1] since version 5.11rc1, but it
was superseded by another patch, which set configure_vlan_while_not_filtering
to true by default since kernel v5.12-rc2 [2].

-Subject: [PATCH] net: dsa: mv88e6xxx: fix vlan setup
-
-Provide an option that drivers can set to indicate they want to receive
-vlan configuration even when vlan filtering is disabled. This is safe
-for Marvell DSA bridges, which do not look up ingress traffic in the
-VTU if the port is in 8021Q disabled state. Whether this change is
-suitable for all DSA bridges is not known.
