[0/5] ath10k: implement PN replay protection for SDIO

HTT High Latency devices (SDIO and USB) need PN replay protection in
host driver, implemented in this patchset. Also support for QCA6174
hw3.2 SDIO devices is enabled as now all the necessary pieces have now
been implemented.

For replay protection of TKIP, CCMP and GCMP
ath10k_htt_rx_pn_check_replay_hl() will check PN to see if the frame
is received before. This is implemented in patch "ath10k: add PN
replay protection for high latency devices"

The replay protection on fragmented MSDU with CCMP and GCMP is done by
ath10k_htt_rx_proc_rx_frag_ind_hl(), implemented in patch "ath10k: add
fragment packet handler for high latency". The fragments will be
reassembled by mac80211 in ieee80211_rx_h_defragment(). Also mac80211
will verify the Michael MIC in ieee80211_rx_h_michael_mic_verify().

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1.
