Introduce CONFIG_XEN to make U-Boot could be used as bootloader
for a virtual machine.
Without bootloader, we could successfully boot up android on XEN, but
we need need bootloader to support A/B, dm verify and etc.

+ Enabling this option will make U-Boot be run as a bootloader
+ for XEN [1] Virtual Machine.
+
+ Xen is a virtual machine monitor (VMM) or a type-1 hypervisor with
support
+ for para-virtualization. Xen can organize the safe execution of
several
+ virtual machines on the same physical system with performance close to
+ native. It is used as the basis for a number of different commercial
and
+ open source applications, such as: server virtualization,
Infrastructure
+ as a Service (IaaS), desktop virtualization, security applications,
+ embedded and hardware appliances.
+ Xen has a special VM called Domain-0 that runs the Dom0 kernel and
allows
+ Xen to use the device drivers for the Domain-0 kernel by default.
