dt-bindings: phy: Update SERDES_MAX to be SERDES_MAX + 1
SERDES_MAX is a valid value to index ctrl->phys in
drivers/phy/mscc/phy-ocelot-serdes.c. But, currently,
there is an out-of-bounds bug in the mentioned driver
when reading from ctrl->phys, because the size of
array ctrl->phys is SERDES_MAX.
Partially fix this by updating SERDES_MAX to be SERDES6G_MAX + 1.
Notice that this is the first part of the solution to
the out-of-bounds bug mentioned above. Although this
change is not dependent on any other one.
