c588ca8734 drivers: xen: events: fix build issues with disabled Xen HVC
Some setups do not use Xen hypervisor console for logging, e.g. they
use emulated PL011 hardware or shared peripherals (real UART). In such
cases Xen HVC will be disabled on a build time and will cause issues in
current driver implementation.

This commit fixes build issues in Xen event channel driver, caused
by absense of console event channel, that is not available when console
config is disabled. Now console related code will be removed when
Xen HVC is turned off.

384d5cfe5d serial: serial_xen: Add Xen PV serial driver
Add support for Xen para-virtualized serial driver. This
driver fully supports serial console for the virtual machine.

Please note that as the driver is initialized late, so no banner
nor memory size is visible.
