24	  Enable Xen hypervisor console driver. Used for Zephyr as
25	  privileged domain (Dom0) or for Zephyr DomU in Dom0less
26	  configuration. Dom0less configuration does not have
27	  privileged domain. Thus, there is no console daemon and Xen
28	  manages all domain outputs through the consoleio interface.

35	  Set init priority for Xen HVC, should be inited before UART

42	  Enable setting of console_io symbol hook for stdout and printk.
43	  Log output will become available on PRE_KERNEL_1 stage. Requires
44	  Xen, compiled with CONFIG_DEBUG flag.
