The PC uses the 8042 microcontroller to talk to the PS/2 keyboard and mouse. Implement a peripheral for the x86 port.

I made a doc with what I've done + what I've found so far!
I am still working on the drivers

[As a sidenote] The doc is not finished yet!! I am still following the Tock book

Please make sure to work with @domnudragota who already has experience with x86 work.
