net: phy: broadcom: Handle irqs on BCM54213PE

The phy specific structure is missing the pointers for handling
interrupts and link change notification. This results in interrupt's
being polled on CM5:

Fix this and copy the existing pointers from BCM54210E, which match the
implementation.

Before:
[3.501498] macb 1f00100000.ethernet eth0: PHY [1f00100000.ethernet-ffffffff:00] driver [Broadcom BCM54213PE] (irq=POLL)

After:
[3.597582] macb 1f00100000.ethernet eth0: PHY [1f00100000.ethernet-ffffffff:00] driver [Broadcom BCM54213PE] (irq=168)
