ac586e2d6a ACPI / PMIC: Use common LPAT table handling functions
The LPAT table processing functions from this modules are moved to a
standalone module with exported interface functions.
Using new interface functions in this module.

491cb357de ACPI / PMIC: AXP288: support virtual GPIO in ACPI table
The same virtual GPIO strategy is also used for the AXP288 PMIC in that
various control methods that are used to do power rail handling and
sensor reading/setting will touch GPIO fields defined under the PMIC
device. The GPIO fileds are only defined by the ACPI code while the
actual hardware doesn't really have a GPIO controller, but to make those
control method execution succeed, we have to install a GPIO handler for
the PMIC device handle. Since we do not need the virtual GPIO strategy,
we can simply do nothing in that handler.

d8139f6311 ACPI / PMIC: support PMIC operation region for XPower AXP288
The Baytrail-T-CR platform firmware has defined two customized operation
regions for PMIC chip Dollar Cove XPower - one is for power resource
handling and one is for thermal just like the CrystalCove one. This patch
adds support for them on top of the common PMIC opregion region code.

b1eea857d8 ACPI / PMIC: support PMIC operation region for CrystalCove
The Baytrail-T platform firmware has defined two customized operation
regions for PMIC chip Crystal Cove - one is for power resource handling
and one is for thermal: sensor temperature reporting, trip point setting,
etc. This patch adds support for them on top of the existing Crystal Cove
PMIC driver.

The reason to split code into a separate file intel_pmic.c is that there
are more PMIC drivers with ACPI operation region support coming and we can
re-use those code. The intel_pmic_opregion_data structure is created also
for this purpose: when we need to support a new PMIC's operation region,
we just need to fill those callbacks and the two register mapping tables.
