s390x: Replace PAGE_SIZE, PAGE_SHIFT and PAGE_MASK

Browse source 
The PAGE_SIZE macro is causing trouble on Alpine Linux since it
clashes with a macro from a system header there. We already have
the TARGET_PAGE_SIZE, TARGET_PAGE_MASK and TARGET_PAGE_BITS macros
in QEMU anyway, so let's simply replace the PAGE_SIZE, PAGE_MASK
and PAGE_SHIFT macro with their TARGET_* counterparts.
