arm64: acpi: Add acpi_get_cpu_uid() for unified ACPI CPU UID retrieval
As a step towards unifying the interface for retrieving ACPI CPU UID
across architectures, introduce a new function acpi_get_cpu_uid() for
arm64. While at it, add input validation to make the code more robust.
Reimplement get_cpu_for_acpi_id() based on acpi_get_cpu_uid() for
consistency, and move its implementation next to the new function for
code coherence.
