[PATCH v2 5/5] powerpc/sparse: Add more assembler prototypes

[Daniel Axtens <dja@axtens.net>]

Another set of things that are only called from assembler and so need
prototypes to keep sparse happy.

Signed-off-by: Daniel Axtens <dja@axtens.net>

---

v2: Fix a couple of issues identified by the 0day bot:
    - different definition of sys_swapendian for 32/64
    - the previous fadump patch fixes a weird interaction with headers
      that the bot picked up.

Again, created semi-programatically and compile-tested against
top-level defconfigs.
