MFC r309345:

The RX_FREEBUFFER registers are a write to increment field.
Writing the full queue size to it every time was makeing it overflow with a
lot of bogus values.

This fixes the interrupt storms on irq 40.

MFC r309347:

MDIO_PHYACCESS_ACK is only valid for read access, remove it from
miibus_writereg.

Reduce the DELAY() between reads while waiting for MII access.
