Move this duplicated definition to ppc_asm.h and remove the
braces which prevent the use of %rN register names

Alex: This is needed to fix the build with Mikey's patch series
that enforce proper register name usage in assembly files.
I'm about to merge the whole lot in powerpc -next, possibly
tomorrow. I've pushed it all to my "test" branch on k.org for
now so I can still rebase.
Please check with whatever you have pending in your or avi's
-next as it's possible that there will be build breakage...
If there is and you can send me a fix, I will slip it in before
the patch that turns on the enforcement, so please have a look
at what I have in 'test' asap.
