Matthew Auld aaeef7a9c8 drm/xe/migrate: rework size restrictions for sram pte emit
We allow the input size to not be aligned to PAGE_SIZE, which leads to
various bugs in build_pt_update_batch_sram() for PAGE_SIZE > 4K systems.
For example if ptes is exactly one gpu_page_size then the chunk size is
rounded down to zero.  The simplest fix looks to be forcing PAGE_SIZE
aligned inputs.
