HW ID page should be able to avoid "or devtypeimu"

While reviewing the compass ordering PR from @bugobliterator I noticed that the "HW ID" page on latest MP beta seems to provide two possibilities to the user for each device id:

So for example below (tested on a CubeBlack) the end of the first line says, "compass DEVTYPE_LSM303D or devtypeimu 2". I think we can do a little better:

- the parameter name starts with "COMPASS_" so we already know we're dealing with a compass so there's not need to present the "or devtypeimu 2" part.
- can't we replace "BUS_TYPE SPI" with just "SPI" and "DEV_TYPE_LSM303D" with just "LSM303D"? For a regular user I just think it's scary enough to try and figure this out... we don't need "bus type" in small letters followed immediately by "BUS_TYPE_" in capitals. I think ideally the top lines should look like this, "COMPASS_DEV_ID:131874, bus type:SPI, bus:4, address:3, LSM303D"


Start by locating the HW ID page implementation and reproduce the displayed compass entry using the example in the issue. Trace how the parameter name, bus type, device type, and devtypeimu text are assembled. Done means the page presents the requested concise format and omits the redundant devtypeimu text for compass parameters.
