With the new generic smp call function helpers, I noticed the code in
smp_message_recv was a single function call in many cases. While
getting the message number from the ipi data is easy, we can reduce
the path length by a function and data-dependent switch by registering
seperate IPI actions for these simple calls.
Originally I left the ipi action array exposed, but then I realized the
registration code should be common too.
The three users each had their own name array, so I made a fourth
to convert all users to use a common one.

Previously the FDT header field boot_cpuid_phys wasn't actually used
on ppc32. Instead the physical boot cpuid was assumed to be 0 for
!CONFIG_SMP.

They don't need to be macros, and having them as inline functions
avoids warnings about unused variables on some configurations when the
argument isn't evaluated.

from include/asm-powerpc. This is the result of a
mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm
Followed by a few documentation/comment fixups and a couple of places
where <asm-powepc/...> was being used explicitly. Of the latter only
one was outside the arch code and it is a driver only built for powerpc.
