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.
