====================
phy: ocelot-serdes: fix out-of-bounds read

This patchset aims to fix an out-of-bounds bug in
the phy-ocelot-serdes driver.

Currently, there is an out-of-bounds read on array ctrl->phys,
once variable i reaches the maximum array size of SERDES_MAX
in the for loop.

Quentin Schulz pointed out that SERDES_MAX is a valid value to
index ctrl->phys. So, I updated SERDES_MAX to be SERDES6G_MAX + 1
in include/dt-bindings/phy/phy-ocelot-serdes.h.

Then I changed the condition in the for loop from
i <= SERDES_MAX to i < SERDES_MAX in order to
complete the fix.

The reason I'm sending this fix as series is because
checkpatch reported an error when I first tried to
integrate the whole solution into a singe patch. So,
changes to dt-bindings should be sent as a separate
patch.

Changes in v3:
 - Post the series to netdev, so Dave can take it.

Changes in v2:
 - Send the whole series to Kishon Vijay Abraham I, so it
   can be taken into the PHY tree.
 - Add Quentin's Reviewed-by to commit log in both patches.
