When looking at my /proc/cpuinfo file:

processor : 0
model name : ARMv7 Processor rev 1 (v7l)
BogoMIPS : 326.86
Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 vfpd32
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x0
CPU part : 0xc05
CPU revision : 1

Hardware : Atmel SAMA5
Revision : 0000

There is no AES flag, how will i be able to enable the AES encryption engine?

AES engine is a driver and not a CPU extension.
This engine's driver is usually enabled in our kernel sama5_defconfig. Have a look at the boot log and you'll see it appearing (running a pre-built demo for instance).
