iommu/omap: Fix printing format for size_t on 64-bit

Print size_t as %zu or %zx to fix -Wformat warnings when compiling on
64-bit platform (e.g. with COMPILE_TEST):

drivers/iommu/omap-iommu.c: In function ‘flush_iotlb_page’:
drivers/iommu/omap-iommu.c:437:47: warning:
format ‘%x’ expects argument of type ‘unsigned int’,
but argument 7 has type ‘size_t {aka long unsigned int}’ [-Wformat=]
