ACPI: Section mismatch ... acpi_map_pxm_to_node

Last of the "Section mismatch" errors from ia64 builds! acpi_map_pxm_to_node()
is defined with attribute __cpuinit, but is called by "normal" kernel functions
acpi_getnode() and acpi_map_cpu2node().

Commit f363d16fbb9374c0bd7f2757d412c287169094c9 moved the data structures on
which this routine operates from __cpuinitdata to regular memory, so this
routine can also move out of init space.
