s390/percpu: Use __PCPU_BEGIN() and __PCPU_END() for inline assemblies

Replace the use of MVIY_PERCPU(), AG_ALT(), and MVIY_ALT() within all
percpu inline assemblies with __PCPU_BEGIN() and __PCPU_END(), since
the begin and end of each inline assembly is the same.

Also use consistent names: e.g. __PCPU_MVIY() and __PCPU_AG() instead of
the previous MVIY_PERCPU() and AG_ALT().

Furthermore extract DEFINE_GR_NUM and UNDEF_GR_NUM which are used to
convert register strings to register numbers.

All of this should make the code more readable. No functional change.
