ARM Packages: Force the SEC modules to be 2K aligned for AArch64

Browse Source 
The AArch64 Vector Table must be aligned on a 2K boundary.
The FDF specification does not support 2K alignment but support 4K.

A clear comment has been added to help integrator to understand why the
assertion fails when porting to a new AArch64 platform.
