XIP has a history of being broken for long periods of time. In 2023, it was
broken for 18 months before getting fixed [1]. In 2024 it was 4 months [2].
And now it is broken again since commit a44fb57221 ("riscv: Add runtime
constant support"), 10 months ago.
These are clear signs that XIP feature is not being used.
I occasionally looked after XIP, but mostly because I was bored and had
nothing better to do.
Remove XIP support. Revert is possible if someone shows up complaining.
