The patch looks okay to me, but I worry that this might fail on boards
which have not connected the phyer's PWERDOWN/INTN pin to anything.
Such designs really need the PHY_POLL working.

Taking a brief glance at the drivers for two such boards I know of
(m5234bcc and an IXP), it looks like their MAC drivers set mii_bus irq
to PHY_POLL, so it might work fine, but this patch still makes me
nervous that some other board might break.

Maybe this should be a kconfig option?

Thanks,
Richard
