ÚPlatformProfileEventHandlera
Event handler for switching PPD profiles based on the
ACPI platform profile
This handler should only invoke a PPD profile change if the
change of the file at PLATFORM_PROFILE_PATH comes from within
the kernel (e.g., when the user presses Fn-L on a Thinkpad laptop).
This is currently detected as the file being modified without
being opened before.
