[PR] ipq806x: kernel 5.10 bump code propose

I can do that.

Unrelated to that:
I am wondering if we should disable the 384000 speed step at the same time as the DTS is modified in any case?

There has been lots of discussion during the years about the somewhat below-expectations performance with "ondemand" governor, and one reason has been CPU / cache frequency scaling from/to 384k vs 600k. I tested with flent yesterday, and eliminating the 384k from the speed table made the latency under load much better. It is not directly related to this DTS/5.10 bump, but might be something that we might consider.
