This patch adds support for QCA2066 firmware patch and NVM downloading.
as the RF performance of QCA2066 SOC chip from different foundries may
vary. Therefore we use different NVM to configure them based on board ID.

There is still no changelog here as I explicitly asked you to add.
You also did not CC all people who have been reviewing your previous
attempts.
If you don't listen to feedback you will never get your patches merged.

Most of this chunk is definitely irrelevant to QCA2066. Please split it
to a separate patch and send both of the patches as a series.
