So the topic of the seed CSR came up on the U-Boot ML in the last few
days:
https://lore.kernel.org/u-boot/20231107212431.GP6601@bill-the-cat
I think we need to document that having zkr in riscv,isa-extensions
means that the CSR is accessible at the privilege level to which that
devicetree has been provided.
