Add support for Inspur platforms to used the platform profile feature.
This will allow users to determine and control the platform modes
between low-power, balanced and performance modes.
Signed-off-by: Ai Chao <[email protected]>
---
v5: Rename inspur-wmi to inspur_platform_profile
v4: Add select ACPI_PLATFORM_PROFILE
v3: Remove input device, using the platform profile interface
v2: Remove Event GUID, remove inspur_wmi_notify and inspur_wmi_notify.
