Add documentation for the amd_3d_vcache sysfs bus platform driver
interface so that userspace applications can use it to change mode

+Description: (RW) AMD 3D V-Cache optimizer allows users to switch
CPU core
+ rankings dynamically.
+
+ This file switches between these two modes:
+ - "frequency" cores within the faster CCD are prioritized
before
+ those in the slower CCD.
+ - "cache" cores within the larger L3 CCD are prioritized before
+ those in the smaller L3 CCD.
+
+ Format: %s.
What is the purpose of "Format: %s"?
Input takes string format either "frequency" or "cache"
I will remove above Format to avoid confusion.
Thanks,
