Hm, I guess documentation should at least say that
iommu_inclusive_mapping is x86 specific, because it's not parsed on
Arm and hence might give the wrong impression that it's actually
acknowledged there.

Albeit I think it would be better to put the parsing in generic
iommu.c, so that the option gets parsed on Arm and
arch_iommu_hwdom_init() can print a warning message about it not
supported on Arm.

Thanks, Roger.
