old code has no deinit functionality for virtual keyboard device.
Which will trigger resource leak when system is reboot.
deinit function is added to:
1. deinit low ps2 based keyboard and mouse
2. release memory/io resource of virtual keyboard device
NOTE: IRQ resource will be handed in pci irq module

Linux kernel CF9 reboot is doing things like:
- read value from 0xcf9
- mask out the value according to the reboot type (warm vs cold)
- BIT OR the value with reboot code
- write the value to 0xcf9
If there are two reboot event and the first one is cold
reboot and the second one is warm reboot, vsbl query
reboot type after the second one and will get code reboot
instead of warm reboot.
We should clear the data of 0xcf9 if guest request cold reboot.
