ath11k: QCA6390 support on Linux

[Kenny Johansson]

Hi

I've tried it out and this time it did not work for me. (Previous
instructions with ath11k-qca6390-bringup-202008181507 did bring it
up.)

My laptop is a Dell XPS 15" with Killer Wi-fi 6 AX500-DBS (2x2) (QCA6390)

Output from dmesg:

sudo dmesg | grep ath11k

Please let me know if I can provide anything more.
