Documentation: riscv: add a section about ISA string ordering in /proc/cpuinfo

Browse source

The RISC-V specs are permissive in what they allow as the ISA string,
but how we output this to userspace in /proc/cpuinfo is quasi uABI.

Formalise this as part of the uABI, by documenting the list of rules
we use at this point in time.
