====================
wireless-next patches for v6.3

First set of patches for v6.3. The most important change here is that
the old Wireless Extension user space interface is not supported on
Wi-Fi 7 devices at all. We also added a warning if anyone with modern
drivers (ie. cfg80211 and mac80211 drivers) tries to use Wireless
Extensions, everyone should switch to using nl80211 interface instead.

Static WEP support is removed, there wasn't any driver using that
anyway so there's no user impact. Otherwise it's smaller features and
fixes as usual.

Note: As mt76 had tricky conflicts due to the fixes in wireless tree,
we decided to merge wireless into wireless-next to solve them easily.
There should not be any merge problems anymore.

Major changes:

cfg80211
 - remove never used static WEP support
 - warn if Wireless Extention interface is used with cfg80211/mac80211 drivers
 - stop supporting Wireless Extensions with Wi-Fi 7 devices
 - support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting

rfkill
 - add GPIO DT support

bitfield
 - add FIELD_PREP_CONST()

mt76
 - per-PHY LED support

rtw89
 - support new Bluetooth co-existance version

rtl8xxxu
 - support RTL8188EU
