qca988x hw chip doesn't support VHT160. It supports VHT80 max.

The `Direct firmware load for ath10k/cal-pci-0000:01:00.0.bin failed with
error -2` and `otp stream is empty, using board.bin contents` are
expected. These are due to the fact OpenWRT had a custom patch for loading
chip calibration data off of flash partition (instead of on-chip EEPROM
which is empty on TP-Link Archer devices among others). In the meantime
upstream driver code changed a bit. This is harmless anyway (other than
being a maintenance burden I suppose).
This should be cleaned up eventually by a volunteer with some spare time
;-)
