[PATCH] riscv: dts: fix isa string for Canaan Kendryte K230

[Yangyu Chen]

The original is a string in dts that has no "zfh" or "zvfh" extension,
but the K230 chip has them, so I am adding them to the dts. This
patch also reordered the Z* extension in the isa string and used
canonical order for the category as the first key and then alphabet
order as the second key to meet RISC-V ISA Extension Naming
Conventions.

I'm just gonna squash this one into the original patch, since I had to
drop it from v6.10 material.

Cheers,
Conor.
