Anders Roxell 2d67222b23 powerpc: Fix build errors with newer binutils
commit 8667d0d64d upstream.

Building tinyconfig with gcc (Debian 11.2.0-16) and assembler (Debian
2.37.90.20220207) the following build error shows up:

  {standard input}: Assembler messages:
  {standard input}:1190: Error: unrecognized opcode: `stbcix'
  {standard input}:1433: Error: unrecognized opcode: `lwzcix'
  {standard input}:1453: Error: unrecognized opcode: `stbcix'
  {standard input}:1460: Error: unrecognized opcode: `stwcix'
  {standard input}:1596: Error: unrecognized opcode: `stbcix'
  ...

Rework to add assembler directives [1] around the instruction. Going
through them one by one shows that the changes should be safe.  Like
__get_user_atomic_128_aligned() is only called in p9_hmi_special_emu(),
which according to the name is specific to power9.  And __raw_rm_read*()
are only called in things that are powernv or book3s_hv specific.
