ARM: Cleanup stack offset cargo cult
Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16
bytes from the stack top. This is unnecessary as on ARM we have a stack
that decrements before storing values. Substracting this offset probably
goes back to the U-Boot version we forked from. Stop this now.
