Add the device tree bindings for the MaxLinear GPY2xx PHYs.

Is the filename ok? I was unsure because that flag is only for the GPY215
for now. But it might also apply to others. Also there is no compatible
string, so..

+    description: |
+      Interrupts are broken on some GPY2xx PHYs in that they keep the
+      interrupt line asserted even after the interrupt status register is
+      cleared. Thus it is blocking the interrupt line which is usually bad
+      for shared lines. By default interrupts are disabled for this PHY and
+      polling mode is used. If one can live with the consequences, this
+      property can be used to enable interrupt handling.
+
+      Affected PHYs (as far as known) are GPY215B and GPY215C.
