fix(build): include Cortex-A78AE cpu file for FVP

So far, the FVP platform.mk file did not include the corresponding file
for Cortex-A78AE, causing the FVP to hang when executing the
plat_reset_handler function. The file is now included to address the
problem and to allow the new CI config for Cortex-A78AE to work
properly.
