This ports over the following commits from the main ARTIQ repo:
- 8740ec3dd52d85084237797881ea137492bfe070
- dbbe8e8ed4f852e623775b7bd3aec818cdd03376
- b9f13d48aa7e2c0652210152b971b21c3c419347
I chose the version from the main repository for two
reasons:
- Explicitly specifying si5324_ref_input every time would
not work for the different Kasli/… hardware versions.
- Having `crystal_ref` as a setting in the configuration
is misleading if it does not actually activate the crystal
for use as a reference (but rather does
`route_crystal_to_ckin2`).

Closes#198#200
Making it a soft panic makes it more involved with a bit of code duplication - setting up mgmt requires setting up the interface and sockets. Maybe can be done a bit cleaner.
