powerpc/pseries: Move VPHN constants into vphn.h
These don't have any particularly good reason to belong in lppaca.h,
move them into their own header.

powerpc/pseries: Move mm/book3s64/vphn.c under platforms/pseries/
hcall_vphn() is specific to pseries and will be used in a subsequent
patch. So, move it to a more appropriate place under
arch/powerpc/platforms/pseries. Also merge vphn.h into lppaca.h
and update vphn selftest to use the new files.

powerpc/mm: Move book3s64 specifics in subdirectory mm/book3s64
Many files in arch/powerpc/mm are only for book3S64. This patch
creates a subdirectory for them.

[mpe: Update the selftest sym links, shorten new filenames, cleanup some
whitespace and formatting in the new files.]

selftests/powerpc: Add test for VPHN
The goal is to verify vphn_unpack_associativity() parses VPHN numbers
correctly. We feed it with a variety of input values and compare with
expected results.
PAPR+ does not say much about VPHN parsing: I came up with a list of
tests that check many simple cases and some corner ones. I wouldn't
dare to say the list is exhaustive though.
