[RFC v1 3/6] riscv: dts: starfive: convert isa detection to new properties

[Conor Dooley]

From: Conor Dooley <conor.dooley at microchip.com>

Convert the jh7100 and jh7110 devicetrees to use the new properties
"riscv,isa-base" & "riscv,isa-extensions".
For compatibility with other projects, "riscv,isa" remains.
