hw/i386/pc: Ensure vmport prerequisites are fulfilled

Browse source 
Since commit 4ccd5fe22f ('pc: add option
to disable PS/2 mouse/keyboard'), the vmport will not be created unless
the i8042 PS/2 controller is enabled. To avoid confusion, let's fail if
vmport was explicitly requested, but the i8042 controller is disabled.
This also changes the behavior of vmport=auto to take i8042 controller
availability into account.
