From: Duke Zhai <duke.z...@amd.com>
BZ #:4640
In V2: Improve coding style.
1.Remove the leading underscore and use double underscore at trailing in C
header files.
2.Remove old tianocore licenses and redundant license description.
3.Improve coding style. For example: remove space between @param.
In V1:
Initial AMD PlatformFlashAccessLib, It provides flash access protocol for
other modules.
