This reverts commit 5c48f1201744233d4f235c7dd916d5196ed20716.

Some device drivers (ath10k) offload part of aggregation including AddBA/DelBA
negotiations to firmware. In such scenario, the PMF configuration of
the station needs to be provided to driver to enable encryption of
AddBA/DelBA action frames.

Signed-off-by: Tamizh chelvam <c_traja@qti.qualcomm.com>

Notes:
	> ath10k change using this mfp configuration will follow.

Oh, it's just some acronym confusion...

MFP = management frame protection
PMF = protected management frames

(or so)
