The marvell PHY reg-init registers for the D-Link DNS-327L are wrong.
Currently the first field is used to set the page 2, but this is
pointless. The usage is not correct, and we are setting the wrong
registers.
Fix it.

Interesting. That is writing to the page register, to change to page
2! So this might of worked with an earlier implementation. But not
now.
