target/riscv: gdb_regno_name takes an enum.

Otherwise it won't compile for me. Not sure why that doesn't affect the automated builds.

There was a mismatch between declaration of gdb_regno_name():

src/target/riscv/gdb_regs.h:123:const char *gdb_regno_name(struct target *target, enum gdb_regno regno);

and the definition:

src/target/riscv/riscv.c:5542:const char *gdb_regno_name(struct target *target, unsigned int regno)

So this fix is definitely correct. I assume that depending on compiler version and -Werror strictness the compiler may complain.

Out of curiosity, I tried two GCC versions locally (8.5.0 and 12.2.1) but wasn't able to reproduce it.

FWIW, I'm running gcc (GCC) 13.2.1 20230801
