[PATCH 3/6] staging: dpaa2-ethsw: setup the STP state for all installed VLANs

[Ioana Ciornei]

Setup the STP state for all VLANs installed on the port. This is also
avoiding the error situation when the DEFAULT_VLAN_ID is not installed
on the port (thus the firmware complains that it cannot setup the
required STP state).
