While doing this use standard names for start/end
so we could use definitions straight from asm-generic
for all the typical symbols.
This also allowed us to drop the use of PROVIDE in the linker
script so sprc is less non-standard on this area.

All noise since we don't have CPU hotplug there. However, they
did expose something very odd-looking in there - poke_viking()
does a bunch of identical btfixup each time it's called (i.e.
for each CPU). That one is left alone for now; just the trivial
misannotation fixes.
