target/riscv: misa to ISA string conversion fix
Some bits in RISC-V `misa' CSR should not be reflected in the ISA
string. For instance, `S' and `U' (represents existence of supervisor
and user mode, respectively) in `misa' CSR must not be copied since
neither `S' nor `U' are valid single-letter extensions.
This commit also removes all reserved/dropped single-letter "extensions"
from the list.
- "B": Not going to be a single-letter extension (misa.B is reserved).
- "J": Not going to be a single-letter extension (misa.J is reserved).
- "K": Not going to be a single-letter extension (misa.K is reserved).
- "L": Dropped.
- "N": Dropped.
- "T": Dropped.
It also clarifies that the variable `riscv_single_letter_exts' is a
single-letter extension order list.
