Firmware 10.2.4.48-2 now supports management frames over HTT feature and has
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX. But as 10.2.4 branch has conflicting HTT ids
patch "ath10k: fix htt t2h message conflicts among firmware revisions" is
needed to fix the issue. Older ath10k versions don't have that fix and to maintain
backwards compatibility we need bump up the FW API to 5 not break older
versions.
