[PATCH] iommu: Fix passthrough option documentation

[Robin Murphy]

Document that the default for "iommu.passthrough" is now configurable.

Fixes: 58d1131777a4 ("iommu: Add config option to set passthrough as default")
Signed-off-by: Robin Murphy <robin.murphy@arm.com>

Joerg, Jon, as a pure doc fix I'll leave it to your discretion as to
whose tree is most appropriate (it shouldn't conflict with the other
IOMMU patches I'm working on)
