iommu/io-pgtable: Replace ->tlb_add_flush() with ->tlb_add_page()
The ->tlb_add_flush() callback in the io-pgtable API now looks a bit silly: - It takes a size and a granule, which are always the same - It takes a 'bool leaf', which is always true - It only ever flushes a single page With that in mind, replace it with an optional ->tlb_add_page() callback that drops the useless parameters.
