media: dt-bindings: samsung,s5p-mfc: Fix iommu properties schemas

The iommus and iommu-names property schemas have several issues. First,
'iommus-names' in the if/then schemas is the wrong name. As all the names
are the same, they can be defined at the top level instead. Then the
if/then schemas just need to define how many entries. The iommus if/then
schemas are also redundant. Best I can tell, the desire was to require 2
entries for "samsung,exynos5433-mfc", "samsung,mfc-v5", "samsung,mfc-v6",
and "samsung,mfc-v8".
