s390/cmma: move arch_set_page_dat() to header file
In order to be usable for early boot code move the simple arch_set_page_dat() function to header file, and add its counter-part arch_set_page_nodat(). Also change the parameters, and the function name slightly. This is required since there aren't any struct pages available in early boot code, and renaming of functions is done to make sure that all users are converted to the new API. Instead of a pointer to a struct page a virtual address is passed, and instead of an order the number of pages for which the page state needs be set.
