	All PS/2 device currently implement various ad-hoc mechanisms to handle multi-byte commands. This is error-prone and makes it hard to implement new devices. Create a buffering mechanism in the base class to avoid this.

2018-04-17	ps2: Factor out PS/2 devices into their own subsystem	Andreas Sandberg
	PS/2 devices are currently emulated both in the i8042 model and the Arm KMI model. This is undesirable since it leads to code duplication. This change introduces a common PS/2 device interface and factor out the x86 keyboard and mouse model. A subsequent commit will implement support for this interface in the Arm KMI model.
