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 SpiFlashDeviceLib for Chachani board flash IC.
  Chachani board use the W25Q256JW as flash IC.
