[RFC v1 2/6] riscv: dts: sifive: convert isa detection to new properties

[Conor Dooley]

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

Convert the fu540 and fu740 devicetrees to use the new properties
"riscv,isa-base" & "riscv,isa-extensions".
For compatibility with other projects, "riscv,isa" remains.
