target/riscv: Add short-isa-string option
Because some operating systems don't correctly parse long ISA extension
string, this commit adds short-isa-string boolean option to disable
generating long ISA extension strings on Device Tree.
For instance, enabling Zfinx and Zdinx extensions and booting Linux (5.17 or
earlier) with FPU support caused a kernel panic.
Operating Systems which short-isa-string might be helpful:
1. Linux (5.17 or earlier)
2. FreeBSD (at least 14.0-CURRENT)
3. OpenBSD (at least current development version)
