Subject: [PATCH v3 4/6] 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.
