perf: RISC-V: Introduce Andes PMU to support perf event sampling
Assign riscv_pmu_irq_num the value of (256 + 18) for the custome PMU
and add SSCOUNTOVF and SIP alternatives to ALT_SBI_PMU_OVERFLOW()
and ALT_SBI_PMU_OVF_CLEAR_PENDING() macros, respectively.
To make use of Andes PMU extension, "xandespmu" needs to be appended
to the riscv,isa-extensions for each cpu node in device-tree, and
make sure CONFIG_ANDES_CUSTOM_PMU is enabled.
