Subject: [PATCH wireless-next v2] wifi: mwifiex: enable host mlme on sdio W8997 chipsets

From: Rafael Beims <rafael.beims@...adex.com>

Enable the host MLME flag to allow supported W8997 chipsets to
use WPA3. This feature requires firmware support (V2 API key), which
the driver validates before activation.

Tested using sdsd8997_combo_v4.bin from commit
211fbc287a0b ("linux-firmware: Update FW files for MRVL SD8997 chips")
