The HIDController class is removed and instead adding SerialIOController class. The HIDController class was a mistake - there's no such thing in real hardware as host controller only for human interface devices (VirtIO PCI input controller being the exception here, but it could be technically treated as serial IO controller too). Instead, we simply add a new abstraction layer - the SerialIO "bus", which will hold all the code that is related to serial communications with other devices. A PS2 controller is simply a serial IO controller, and the Intel 8042 Controller is simply a specific implementation of a PS2 controller.
