drivers: ethernet: Kconfig: Remove redundant 'default n' properties

Bool symbols implicitly default to 'n'. A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you want to override a 'default y' on the base definition of the symbol. It isn't used like that on any of these symbols though, and is inconsistent. This will make the auto-generated Kconfig documentation have "No defaults. Implicitly defaults to n." as well, which is clearer than 'default n if ...' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>
