During migration to HWMv2 separate specific defconfig file was removed for GICv3 version of virtual xenvm boards. It worked fine before commit 0be0d21 ("cmake: modules: extensions: Revert using common board files") significantly changed build behavior, but did not return previously removed file. This led to build/runtime issues, when some of the Kconfig options were not selected. Return GICv3 specific defconfig to board directory to fix configuration problems.

This reverts commit 7c90f1b. Xen initialization maps enlighten page to Zephyr memory and also initializes Xen event channels. It is used for communication between Xen domains and based on interrupt connected to domain virtual GIC. Moving event channel initialization to arch_kernel_init() make it call irq_enable() when GIC is not initialized. Since GIC is initialized on PRE_KERNEL_1 stage, this lead to fatal error during boot. Revert these changes to make xenvm operable again. Signed-off-by: Dmytro Firsov <[email protected]>
