powerpc/64s: move stack SLB pinning out of line from _switch

The large hunk of SLB pinning in _switch asm code makes it more
difficult to see everything else that's going on. It is a less important
path now, so icache and fetch footprint overhead can be avoided.

Move context switch stack SLB pinning out of line.
