The bits at at lane->iddq are actually IDDQ_DISABLE bits, so this is the
wrong way around: having iddq = <0> in device tree leads to the device
turning off. So either the DT property should be renamed or the branches
of the if here should be switched around.
v2 used the wrong variable so the else branch ended up being chosen each
time, this also meant that SATA worked by chance.
