ARM: SMP: use more sane register allocation for __fixup_smp_on_up

commit 0eb0511d176534674600a1986c3c766756288908 upstream.

Use r0,r3-r6 rather than r0,r3,r4,r6,r7, which makes it easier to
understand which registers can be modified.  Also document which
registers hold values which must be preserved.
