dsa: add support for the Marvell 88E6095/6095F switch chips
Add support for the Marvell 88E6095/6095F switch chips. These
chips are similar to the 88e6131, so we can add the support to
mv88e6131.c easily.
Thanks to Gary Thomas <gary@mlbassoc.com> and Jesper Dangaard
Brouer <hawk@diku.dk> for testing various patches.
