Add support for PLIC interrupt controller as per RISC-V PLIC specs.

How have you tested this?

I am still not able to get UART interrupt working with PLIC. I think my sw driver needs some change.

What are the area costs of adding the PLIC to the system?

LUTs increased from 6686 to 6790, FFs increased from 6279 to 6411.

I'm converting this PR to draft until you have a successful UART interrupt firing.
