Commit Message

Oleksii Kurochko Sept. 7, 2023, 3:16 p.m. UTC 
asm/vm_event.h is common for ARM and RISC-V so it will be moved to
asm-generic dir.

Original asm/vm_event.h from ARM was updated:
 * use SPDX-License-Identifier.
 * update comment messages of stubs.
 * update #ifdef
 * instead of "include <public/domctl.h>" -> "public/vm_event.h"

As vm_event.h was moved to asm-generic then it is needed to create
Makefile in arm/include/asm/ and add generated-y += vm_event.h to
it.
