Let driver parse DPP frames from upper layer and do conresponding
configuration to firmware.
This change supports DPP handshake based on wpa_supplicant v2.9.

From: Kurt Lee <kurt.lee@cypress.com>
1. If firmware supports 4-way handshake offload but not supports DPP
4-way offload, when user first connects encryption network, driver will
set "sup_wpa 1" to firmware, but it will further result in DPP
connection failure since firmware won't send EAPOL frame to host.
2. Fix DPP AP mode handling action frames.
3. For some firmware without fwsup support, the join procedure will be
skipped due to "sup_wpa" iovar returning not-support. Check the fwsup
feature before do such iovar.

It is not a good practice to fix multiple issues in one patch. Please
break this up.

The two authentication type refer to equal value: DPP_AKM_SUITE_TYPE &
RSN_AKM_PSK (both =2)
So I can not directly place DPP_AKM_SUITE_TYPE into switch case.
It's more reasonable that we firstly check if it's DPP by
brcmf_valid_dpp_suite
- need to check WFA_OUI and DPP_AKM_SUITE_TYPE
Then go to the other cases.

Being firmware dependent is exactly the problem here. The user
functions of this macro are in common code path so this bit could go
to firmware from any vendor. A mechanism should be in place to only
set this bit when the driver is working with a infineon/cypress
firmware.

Currently we don't have such mechanism.
Please abandon this review series.
