Just tried this on an QCA9984 which doesn't seem to have the calibration data
in the PCI EEPROM.

It works when I use the pre-cal data as calibration data. The checksum in the
pre-cal seems to be correct. Also the pre-cal data from 0:ART for the 2.4GHz
and 5GHz QCA4019 seem to work perfectly fine.
Anything which I could have missed or what I could test? Btw. I've also tested
the non-ct firmware (aka the official one from QCA).
