To use FDT-based probing for hardware support of the PMU extensions and introduce Andes PMU alternatives, we first convert T-Head's PMU to CPU feature alternative. Its non-standard local interrupt is assigned to bit 18 in the custom S-mode local interrupt enable/pending registers (slie/slip), while the interrupt cause is (256 + 18).
