powerpc/e500: Simplify pte_mkexec()
Commit b6cb20fdc273 ("powerpc/book3e: Fix set_memory_x() and
set_memory_nx()") implemented a more elaborated version of
pte_mkwrite() suitable for both kernel and user pages. That was
needed because set_memory_x() was using pte_mkwrite(). But since
commit a4c182ecf335 ("powerpc/set_memory: Avoid spinlock recursion
in change_page_attr()") pte_mkwrite() is not used anymore by
set_memory_x() so pte_mkwrite() can be simplified as it is only
used for user pages.
