RISC-V: Make riscv_is_mapping_symbol stricter
riscv_is_mapping_symbol currently accepts any symbol that starts with $x
or $d. This patch makes the check more strict, requiring exactly $x, $d,
or $xrv. It also makes use of this stricter mapping in
riscv_is_valid_mapping_symbol.
ChangeLog:
* bfd/cpu-riscv.c (riscv_elf_is_mapping_symbols): Match only
strings that are exactly $x, $d, or $xrv.
* opcodes/riscv-dis.c (riscv_is_valid_mapping_symbol): Use
riscv_elf_is_mapping_symbols.
