riscv: Add unused attribute to some registers.hh constants
Three of the constants defined in arch/riscv/registers.hh (ReturnValueReg, SyscallNumReg, and SyscallPseudoReturnReg) may cause the compiler to warn that they are unused, which results in an error. This patch adds M5_VAR_USED attributes to them to stop this.
