arch: arm/xen: add putc() for debugging

This new function, xen_debug_putc(), is intended to be used to
enable CONFIG_DEBUG_UART on xen guest.

Please note that the underlying functionality in Xen is available
only when Xen is configured with !NDEBUG but is much simpler than
a generic HYPERVISOR_console_io().
