ArmPlatformPkg: Introduced 'ArmPlatformSecLib'
The function only used in Secure Firmware used to be mixed with the Non-Secure/Normal functions in ArmPlatformLib. When the Secure Firmware was not required for some platforms (eg: BeagleBoard), these functions were empty functions. This new interface has been created to clean the ArmPlatformLib interface between the SEC and PEI phases.
