mdio: fix CONFIG_MDIO_DEVRES selects

The newly added rtl9300 driver needs MDIO_DEVRES:

x86_64-linux-ld: drivers/net/mdio/mdio-realtek-rtl9300.o: in function `rtl9300_mdiobus_probe':
mdio-realtek-rtl9300.c:(.text+0x941): undefined reference to `devm_mdiobus_alloc_size'
x86_64-linux-ld: mdio-realtek-rtl9300.c:(.text+0x9e2): undefined reference to `__devm_mdiobus_register'
Since this is a hidden symbol, it needs to be selected by each user,
rather than the usual 'depends on'. I see that there are a few other
drivers that accidentally use 'depends on', so fix these as well for
consistency and to avoid dependency loops.

Fixes: 37f9b2a6 ("net: ethernet: Add missing depends on MDIO_DEVRES")
Fixes: 24e31e47 ("net: mdio: Add RTL9300 MDIO driver")
