Srinivas Pandruvada c55d62820e ACPI / LPAT: Common table processing functions
Since LPAT table processing is also required for other thermal drivers,
moved LPAT table related functions from intel PMIC driver (intel_pmic.c)
to a stand alonge module with exported interfaces.
In this way there will be no code duplication.
