Seems you have BR2_PACKAGE_WPA_SUPPLICANT already enabled...

....so you did not use plain raspberrypi3_defconfig (or made already some
changes to it)...., from your given examples I suspect your followed this
receipe [1]? Please provide next time your .config/defconfig (after
savedefconfig) files...

I see no 'brcmfmac' lines in your dmesg output, maybe BR2_PACKAGE_RPI_WIFI_FIRMWARE
not enabled? Or your did not change to BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV?

Or something with your config files, make sure to only use plain spaces (after copying
from your email I got no plain spaces as indent but some UTF-8 spaces)...

raspberrypi3_defconfig with the following changes works for me:

+BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV=y

+BR2_PACKAGE_RPI_WIFI_FIRMWARE=y
+BR2_PACKAGE_DHCPCD=y
+BR2_PACKAGE_WPA_SUPPLICANT=y

Regards,
Peter
