Subject: [PATCH net-next] net: stmmac: set phy to use polling by default

From: Dinh Nguyen <dinguyen@...era.com>

mii_irq[] array is never initialized anywhere in the driver, thus mii_irq[]
will always equate to zero. So, for the case where the PHY does not have an
irq, we should use PHY_POLL for that situation.
