[PATCH 2/3] wpa_supplicant: expose DPP config object PSK/PMK

[Michal Kazior]

From: Michal Kazior <michal at plume.com>

Hostapd was already exposing this. There's no
reason not to expose it in wpa_supplicant.

This allows 3rd party apps interacting with the
control interface to handle DPP events to get
configs instead of needing to dance around with
update_config=1 and save_config.
