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

"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.

staging: r8188eu: convert switch to if statement in mgt_dispatcher()

The 'switch (GetFrameSubType(pframe))' in mgt_dispatcher() has only
one case that does something different than the default case. Convert
the switch to an if statement to improve readability.

Convert DBG_88E macro calls in core/rtw_ap.c to use netdev_dbg when they
may display useful information, and remove erroneous DBG_88E calls
entirely.

This leaves six empty static functions which only had DBG_88E calls,
so just remove them:

update_bcn_fixed_ie
update_bcn_htcap_ie
update_bcn_htinfo_ie
update_bcn_rsn_ie
update_bcn_wpa_ie
update_bcn_wmm_ie

also modifying the if blocks/switch cases that invoke them to no longer do
so. This goes further towards the goal of removing this non-standard
debugging code.
