also update MAINTAINERS file with this new information

Description:	Reading this file tells if the AMD Platform Management(PMF)

		Cool n Quiet Framework(CnQF) feature is enabled or not.



		This feature is not enabled by default and gets only turned on

		if OEM BIOS passes a "flag" to PMF ACPI function (index 11 or 12)

		or in case the user writes "on".



		To turn off CnQF user can write "off" to the sysfs node.

		Note: Systems that support auto mode will not have this sysfs file

		available.
