I couldn't resist to have a quick look into the device tree file(s) in the kernel sources of Bianbu Linux:

see here: https://gitee.com/bianbu-linux/linux-6.6/blob/bl-v2.0.y/arch/riscv/boot/dts/spacemit/k1-x.dtsi

On a quick look (didn't check entry by entry) the 'riscv,isa-extensions' entries per cpu seems to match your table.

Anyway as I said before, I think this does not need to reflect the real capabilities of the SOC too.
