The default target should be "generic", as Cortex-A53 includes
optional ISA features (CRC and CRYPTO) that are not required for
architectural compliance. The key difference between generic (which
already uses the cortexa53 pipeline model for scheduling) is the
absence of any optional ISA features in the "generic" target.
