This is mainly to reduce clutter in `subsys/logging`, but also to make backend management slightly easier. Signed-off-by: Christopher Friedt <cfriedt@fb.com>

Set SWO output frequency. Value 0 will select maximum frequency
|
|
supported by the given MCU. Not all debug probes support high
|
|
frequency SWO operation. In this case the frequency has to be set
|
|
manually.
|
|
|
|
SWO value defined by this option will be configured at boot. Most SWO
|
|
viewer programs will configure SWO frequency when attached to the
|
|
debug probe. Such configuration will persist only until the device
|
|
reset. To ensure flawless operation the frequency configured here and
|
|
by the SWO viewer program has to match.
