  2. ACPI: RISCV: Add NUMA support based on SRAT and SLIT 

    Add acpi_numa.c file to enable parse NUMA information from
ACPI SRAT and SLIT tables. SRAT table provide CPUs(Hart) and
memory nodes to proximity domain mapping, while SLIT table
provide the distance metrics between proximity domains.

  4. ACPI: NUMA: Make some NUMA related parse functions common 

    The acpi_numa_slit_init(), acpi_numa_memory_affinity_init()
and acpi_parse_cfmws() functions are common enough to be used
on platforms that support ACPI_NUMA(x86/arm64/loongarch).
Remove the condition to avoid long defined(CONFIG_ARCH) check
when new platform(riscv) support was enabled.

  5. ACPI: NUMA: Remove ARCH depends option in ACPI_NUMA Kconfig 

    x86/arm64/loongarch would select ACPI_NUMA by default and riscv
would do the same thing, so the dependency is no longer needed
since these are the four architectures that support ACPI.
