net: dsa: mv88e6xxx: Fix the max_vid definition for the MV88E6361
[ Upstream commit 1833d8a26f057128fd63e126b4428203ece84684 ]
According to the Marvell datasheet the 88E6361 has two VTU pages
(4k VIDs per page) so the max_vid should be 8191, not 4095.
In the current implementation mv88e6xxx_vtu_walk() gives unexpected
results because of this error. I verified that mv88e6xxx_vtu_walk()
works correctly on the MV88E6361 with this patch in place.
