The current bcm63xx_enet driver doesn't asign the internal phy IRQ. As a
result of this it works in polling mode.
Fix it using the phy_device structure to assign the platform IRQ.
Tested under a BCM6348 board. Kernel dmesg before the patch:
Broadcom BCM63XX (1) bcm63xx_enet-0:01: attached PHY driver [Broadcom
BCM63XX (1)] (mii_bus:phy_addr=bcm63xx_enet-0:01, irq=POLL)
After the patch:
Broadcom BCM63XX (1) bcm63xx_enet-0:01: attached PHY driver [Broadcom
BCM63XX (1)] (mii_bus:phy_addr=bcm63xx_enet-0:01, irq=17)
Pluging and uplugging the ethernet cable now generates interrupts and the
PHY goes up and down as expected.
