Update to kernel 5.15 / tegra 36.3 for Orin NX

[deniz-hofmeister]

Dear ant micro,

I started looking into compiling your bsp for orin NX, but with the latest nv tegra.

I see that you forked the linux repo and applied changes onto that fork as described here: f5dd419...a086158

is it save to assume that simply forking the linux kernel again, but for 5.15, and applying those changes to that, would result in a working build for kernel 5.15 / tegra 36.3? or would that be rather naive? What would be key points to consider / be aware of? Are there breaking changes?

Greetings and thank you for your work on this base board, it's awesome!
