No description provided.

The firmware for AzureWave AW-NB197SM is from
https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/
Cypress-Linux-WiFi-Driver-Release-FMAC-2021-05-27/td-p/277394

Also, since we will be switching to backported brcmfmac driver
instead of the Rockchip wifi stack, we need to rename the other
firmware and nvram to match what the new driver expects.

We will install them instead using packagegroups

@balena-ci I self-certify!

We switch from Rockchip WiFi stack to brcmfmac driver
backported from kernel version v5.4.18

This backported driver was taken from
https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/
Cypress-Linux-WiFi-Driver-Release-FMAC-2021-05-27/td-p/277394

This new driver has no known stability issues when used with
AzureWave AW-NB197SM modules (the Rockchip dhd driver / firmware
combination crashes frequently).
