attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.

This driver adds support for Dynamic Platform and Thermal Framework
(DPTF) Platform Power Participant device (INT3407) support.
This participant is responsible for exposing platform telemetry such as:
max_platform_power
platform_power_source
adapter_rating
battery_steady_power
charger_type
These attributes are presented via sysfs interface under the INT3407
platform device:
$ls /sys/bus/platform/devices/INT3407\:00/dptf_power/
adapter_rating_mw
battery_steady_power_mw
charger_type
max_platform_power_mw
platform_power_source
`
ACPI methods description used in this driver:
PMAX: Maximum platform power that can be supported by the battery in
mW.
PSRC: System charge source,
0x00 = DC
0x01 = AC
0x02 = USB
0x03 = Wireless Charger
ARTG: Adapter rating in mW (Maximum Adapter power) Must be 0 if no
AC adapter is plugged in.
CTYP: Charger Type,
Traditional : 0x01
Hybrid: 0x02
NVDC: 0x03
PBSS: Returns max sustained power for battery in milliWatts.
The INT3407 also contains _BTS and _BIX objects, which are compliant to
ACPI 5.0, specification. Those objects are already used by ACPI battery
(PNP0C0A) driver and information about them is exported via Linux power
supply class registration.
