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. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
