net: phy: rework Kconfig settings for MDIO_BUS
I still see build errors in randconfig builds and have had this patch for a while to locally work around it: drivers/built-in.o: In function `xgene_mdio_probe': mux-core.c:(.text+0x352154): undefined reference to `of_mdiobus_register' mux-core.c:(.text+0x352168): undefined reference to `mdiobus_free' mux-core.c:(.text+0x3521c0): undefined reference to `mdiobus_alloc_size' The idea is that CONFIG_MDIO_BUS now reflects whether the mdio_bus code is built-in or a module, and other drivers that use the core code can simply depend on that, instead of having a complex dependency line.
