dsa: Allow core and drivers to be built as modules
Change the kconfig types to tristate and adjust the condition for declaring net_device::dsa_ptr to allow for this. Adjust the makefile so that if NET_DSA_MV88E6123_61_65=y and NET_DSA_MV88E6131=m or vice versa then both drivers are built-in. We could leave these options as bool and make NET_DSA_MV88E6XXX a user-selected option, but that would break existing configurations.
