Subject: [PATCHv2] ath11k: add raw mode and software crypto support

Adding raw mode tx/rx support. Also, adding support
for software crypto which depends on raw mode.

To enable raw mode tx/rx:
insmod ath11k.ko frame_mode=0

To enable software crypto:
insmod ath11k.ko crypto_mode=1

These modes could be helpful in debugging crypto related issues.

Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1

Did you test this at all? Because to me it looks like in
ath11k_init_wmi_config_ipq8074() this is overwritten with:

config->rx_decap_mode = TARGET_DECAP_MODE_NATIVE_WIFI;

So I can't see how this would even work. I noticed this while I was
cleaning up ath11k_wmi_cmd_init(). I'll send a patch soon, please test
that and let me know if it works.

My bad it seems my tree is bit older, sorry for the confusion.
Also I noticed, .wmi_init_config of ipq8074_ops is registered with "
ath11k_init_wmi_config_qca6390()" Is that correct?
If that is correct, then I don't see ath11k_init_wmi_config_ipq8074()
is called from any other place.
I will send one patch to fix this issue. Please correct me if I am
wrong.
