staging: wfx: map 'compatible' attribute with board name

Browse source 
"WF200" only designates the chip. To make a WiFi board, the chip must be
associated with an antenna. The antenna configuration is located in
separate files (aka PDS files in Silabs wording). Currently, user has to
write in his DT something like:

    compatible = "silabs,wf200";
    config = "brd4001a.pds";

It is far better to embed a list of known boards (chip + antenna) in the
driver. So the user just have to declare:

    compatible = "silabs,brd4001a";

This patch add the configurations for the evaluation boards sold by
Silabs. To provide a full plug-and-play experience, the associated PDS
files[1] will be available in linux-firmware.

This patch does not break compatibility with existing setups.
