logging: Introduce new "DDEV" category for device-specific code

The DMAIN category got too overloaded.  Let's have the code in
Transceive52M/device/* use the new DDEV category.

Also, in some cases the log levels have been adjusted to ensure
that enabling INFO level should not result in a complete overflow
of messages during normal operation.
