Jacob Pan 6306e68a63 Thermal: int3400_thermal: use acpi_thermal_rel parsing APIs
ACPI _TRT and _ART parsing code has been moved to acpi_thermal_rel such
that it can be used by other devices in the future. Use the parsing APIs
in acpi_thermal_rel.c instead.

Jacob Pan 52b1c69d7e Thermal: int340x_thermal: expose acpi thermal relationship tables
ACPI 4.0 introduced two thermal relationship tables via _ART
(active cooling) and  _TRT (passive cooling) objects. These
tables contain many to many relationships among thermal sensors
and cooling devices.

This patch parses _ART and _TRT and makes the result available to
the userspace via an misc device interface. At the same time,
kernel drivers can also request parsing results from internal
kernel APIs.

The results include source and target devices, influence, and
sampling rate in case of _TRT. For _ART, the result shows source
device, target device, and weight percentage.

Lan Tianyu 4384b8fe16 Thermal: introduce int3403 thermal driver
ACPI INT3403 device object can be used to retrieve temperature date
from temperature sensors present in the system, and to expose
device' performance control.

The previous INT3403 thermal driver supports temperature reporting only,
thus remove it and introduce this new & enhanced one.

Aaron Lu 77e337c6e2 Thermal: introduce INT3402 thermal driver
ACPI INT3402 device object could report temperature for the memory module.
To expose such information to user space, a thermal zone device is registered
for it so that the thermal sysfs interface can expose such information for
userspace to use.
