the new introduced code which initialized the precal data for new 
chipsets will break QCA99XX support.
so ath10k fails to initialize.
i commented out
ret = ath10k_core_pre_cal_config(ar);
  ret = ath10k_core_pre_cal_download(ar);

to get it working again. this might not affect real pcie cards. but on 
IPQ8064 based boards with on board wifi cards it shows that behaviour.

in addition this message here floods the kernel log
[125917.204121] ath10k_pci 0001:01:00.0: failed to increase tx mgmt 
pending count: -16, dropping
but it has no further visible side effects
