Mem: Determine bus block size during initialisation

This patch moves the block size computation from findBlockSize to
initialisation time, once all the neighbouring ports are connected.

There is no need to dynamically update the block size, and the caching
of the value effectively avoided that anyhow. This is very similar to
what was already in place, just with a slightly leaner implementation.
