[RFC 2/2] RISC-V: resort all extensions in "canonical" order

[Conor Dooley <conor.dooley@microchip.com>]

Per the comment in cpu.c, re-sort all lists/tables/enums/whatever in
arch/riscv (apart from KVM) in the current edition of what the isa
manual considers to be "canonical" order.

None of this is in uapi, so we are free to re-order it? I'm never sure
when it comes to hwcap...
