CM5 features the same Broadcom BCM54213PE phy for ethernet as present on pi5, but with a different mdio address (0 instead of 1 on pi5). Fix this and use correct mdio address 0. While at it set interrupt_parent to rp1_gpio instead of gpio (which is an alias to the former) as this is the handle already used in this block. Signed-off-by: Nicolai Buchwitz <[email protected]>
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.

While working on the eee support for rp1's macb driver, I noticed that CM5 defines a phy interrupt, but it isn't used at all. It's caused by missing pointers in the ops struct of BCM54213PE. Also the mdio address differes from pi5 (probably different strapping on the board?), which is fixed by this series.
