Before this patch, the address of uart0 is directly modified, because
there's only one uart0 back then. Now a newer version of Zephyr is used
and more uarts are added. We can now choose uart1, which has the right
address.

Because currently Xen only provides one uart, the uarts that only
available on baremetal have to be disabled.
