[PATCH v3 3/5] ACPI/NUMA: Remove architecture dependent remainings

With the removal of the Itanium architecture [1] the last architecture
dependent functions:

acpi_numa_slit_init(), acpi_numa_memory_affinity_init()

were removed. Remove its remainings in the header files too an make
them static.

[1] commit cf8e8658100d ("arch: Remove Itanium (IA-64) architecture")
