Remove all table size config for new adapters

[puddly]

I believe all of the config affecting table sizes no longer works with newer versions of EmberZNet. The source route table size, for example, is a compile-time constant that generates an array of that size in memory. There doesn't appear to be a way to grow or shrink it.

The specific EZSP version where these config options start taking effect needs to be determined, as right now we apply it for all adapters supporting EZSPv7 and above.
