James Morse b37f5f0f84 arm64: acpi: Move get_cpu_for_acpi_id() to a header 
[ Upstream commit 8d34b6f17b ]

ACPI identifies CPUs by UID. get_cpu_for_acpi_id() maps the ACPI UID
to the Linux CPU number.

The helper to retrieve this mapping is only available in arm64's NUMA
code.

Move it to live next to get_acpi_id_for_cpu().
