Kernel: Introduce a new super class called HIDController

Browse source 
Use the new class in HID code, because all other HID device controllers
will be using this class as their parent class.

Hence, we no longer keep a reference to any PS/2 device in HIDManagement
and rely on HIDController derived classes to do this for us.

It also means that we removed another instance of a LockRefPtr, which
is designated to be removed and is replaced by the better pattern of
SpinlockProtected<RefPtr<>> instead.
