arch/riscv: Configure delegation only if S-mode is supported
On the FU540 the bootblock runs on a core without lesser privilege
modes, so the medeleg/mideleg CSRs are not implemented on that core,
leading to a CPU exception when these CSRs are accessed.
Configure medeleg/mideleg only if the misa register indicates that
S-mode is implemented on the executing RISC-V core.
