Wi-Fi: HP ZBook 17 G2

According to <https://bsd-hardware.info/?probe=1ef99f31dd#d12>, iwm(4) 
should work.

Neither wpa_gui (with wpa_supplicant-devel 2021.06.14) nor 
net-mgt/wifimgr can detect any network.

What am I missing?

/etc/rc.conf includes:

create_args_wlan0="country GB regdomain etsi"
wlans_iwm0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"
