        gdb/riscv: Fix register access for register aliases

broke the CSR names for RISC-V, now all of the CSRs have names like,
csr0, csr1, csr2, etc.  This commit restores the previous
user-friendly names.

gdb/ChangeLog:

	* riscv-tdep.c (riscv_register_name): Use the user-friendly names
	for CSRs.
