Support for QCA6174 [168c:003e]

Hello,


I managed to get it (sort of) working with the eeprom extracted from the 
windows
driversand thefirmware from kvalo's ath10k-repo on GitHub.See more details
below.

Unfortunately I only get a bandwidth of about 2Mb/s connected to a 
54Mb/s AP.Is
this a known limitation to ath10k right now, or may there be a way to get it
working at full speed?


Also, thank You Michał for pointing me the right direction and helping 
make it
usable, at least.
