Currently hyperv-iommu is implemented in a x86 specific way, for
example, apic is used. So make the HYPERV_IOMMU Kconfig depend on X86
as a preparation for enabling HyperV on architecture other than x86.

Without this patch, I could observe compile error:
| drivers/iommu/hyperv-iommu.c:17:10: fatal error: asm/apic.h: No such
| file or directory
| 17 | #include <asm/apic.h>
| | ^~~~~~~~~~~~
, after apply Michael's ARM64 on HyperV enablement patchset.
