Mention that the interrupt line is just asserted for a random period of
time, not the entire time.

       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.
