ramips: mt7620: Enable PHY aneg of Lava LR-25G001

In 20b09a2125 Lava LR-25G001 router have problem with two inactive
ethernet ports. JBOOT bootloader didn't configure ethernet devices by default.
The same situation was there. It is required to enable all phy ports.
This is fragment of stock bootlog:

switch reg write_athr offset=90, value=2b0
switch reg write_athr offset=8c, value=2b0
switch reg write_athr offset=88, value=2b0
switch reg write_athr offset=84, value=2b0
switch reg write_athr offset=80, value=2b0

This patch adds proper registers configuration ar8337 initvals.
0x2b0 value causes force flow control configuration, 0x1200 was used
instead (flow control config auto-neg with phy). [1]

When switch is now ok, let's fix port numeration too.

Fixes: 20b09a2125 ("ramips: add support for Lava LR-25G001")
