aes-128 coprocessor

[DanielTaoHuang123]

build a simple aes-128 coprocessor; probably need MMIO to actually use it

[TheDeepestSpace]

this is really cool, is this from the asic hackathon?

also if its mmio we can move it to peripherals repo once it's setup a bit more

[DanielTaoHuang123]

yes I picked it up from the hackathon
the aes core itself is working, just that it's not connected anywhere; i think a normal way to use it is through mmio. I can move it to peripherals repo later
