powerpc/iommu: Fix initialisation of DART iommu table
Commit d084775738b746648d4102337163a04534a02982 switched the generic powerpc iommu backend code to use the it_page_shift field to determine page size. Commit 3a553170d35d69bea3877bffa508489dfa6f133d should have initiliased this field for all platforms, however the DART iommu table code was not updated. This commit initialises the it_page_shift field to 4K for the DART iommu. Signed-off-by: Alistair Popple <alistair@popple.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
