As a small break from the axi stuff, I tackled the other issue from the original thread - get_destination_status not being implemented (being hardcoded to return true on destination == 0).

This one was just a bit tricky - yeah I used messages, but to use messages/channels freely, the code must be a part of the kernel submodule in runtime, since channels are not public statics and I would rather keep them that way. So that was moved there. Not sure if this could be condensed nicely somewhere else, instead of making a new module.

Tested on Kasli-SoC master with connected Kasli 1.1 satellite. The function in experiments (in Python) does behave as intended.

It's just one small function, what about just putting it in src/kernel/core1.rs?
