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 Signed-off-by: Yin Fengwei <fengwei.yin@intel.com> Acked-by: Eddie Dong <Eddie.dong@intel.com>
