Initially, REMAP only worked with big pages but in some cases only small pages are supported where REMAP functionality is also needed. This cleans up some page size assumptions. In particular, on a remap request, the nvgpu_vm_area is found from the passed in VA, but can only be done from virt_offset_in_pages if we're also told the page size. This now occurs from _PAGESIZE_ flags which are required by both map and unmap operations.
