The current interdepencies between the PrePeiCore SEC module, the platform PEIM and ArmPlatformLib is a bit awkward: due to the fact that ArmPlatformLib is also used by SEC modules, we cannot use PEI specific facilities in the implementation of ArmPlatformGetBootMode. However, given that we call that library function /after/ invoking PlatformPeiLib, there is no way for that library to set the boot mode other than resorting to tricks like notification callbacks on arbitrary unrelated events. ArmPlatformLib should probably be phased out anyway, given its quirky nature, but for now, let's fix this particular issue by deferring the call to PlatformPeim() to after the point where we set the boot mode by calling ArmPlatformGetBootMode (). While we're at it, clean up the code slightly by using PeiServicesLib instead of doing double pointer dereferencing.
