Kconfig: Introduce CONFIG_XEN

Browse source 
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.

bool "Select U-Boot be run as a bootloader for XEN Virtual Machine"
help
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.
