Patch 1/4 add RISC-V specific acpi_numa.c file to parse NUMA information from SRAT and SLIT ACPI tables. Patch 2/4 add the common SRAT RINTC affinity structure handler. Patch 3/4 change the ACPI_NUMA to a hidden option since it would be selected by default on all supported platform. Patch 4/4 replace pr_info with pr_debug in arch_acpi_numa_init() to avoid potential boot noise on ACPI platforms that are not NUMA.
