[PATCH] brcmfmac: Add WPA3 Personal with FT to supported cipher suites

[Paweł Drewniak <czajernia@xxxxxxxxx>]

This allows the driver to connect to BSSIDs supporting SAE with 802.11r.
Tested on Raspberry Pi 4 Model B (STA) and UniFi 6LR/OpenWRT 21.02.0-rc2.
AP was set to 'sae-mixed' (WPA2/3 Personal).
