Legacy USB Support

Legacy USB support refers to USB mouse and keyboard support. If this option is not enabled,
any attached USB mouse or keyboard will not become available until a USB compatible
operating system is fully booted with all USB drivers loaded. When this option is enabled,
any attached USB mouse or keyboard can control the system even there is no USB driver
loaded on the system.

EHCI Hand-off

This is a workaround for OSes without EHCI hand-off support. The EHCI ownership change
should be claimed by EHCI driver.
