Quite a few of the existing supported chips that use
mv88e6085_g1_ieee_pri_map as ->ieee_pri_map (including, incidentally,
mv88e6085 itself) actually have a reset value of 0xfa50 in the
G1_IEEE_PRI register.
The data sheet for the mv88e6095, however, does describe a reset value
of 0xfa41.
So rather than changing the value in the existing callback, introduce
a new variant with the 0xfa50 value. That will be used by the upcoming
mv88e6250, and existing chips can be switched over one by one,
preferably double-checking both the data sheet and actual hardware in
each case - if anybody actually feels this is important enough to
care.
