gdb/riscv: Remove partial target description support
Some parts of the target description support were committed with the initial riscv patch. As target descriptions are not currently supported on riscv this commit removes the two pieces for code that relate to target description support. It is expected that target description support will be added in the future, at which point this, or similar code will be added back. gdb/ChangeLog: * riscv-tdep.c (riscv_register_name): Remove target description support. (riscv_gdbarch_init): Remove target description check.
