powerpc: mpc83xx: Minimize r1 modification
The r1 register is modified several times during the cache-ram setup of
the MPC83xx SoCs.
Since this SP modification confuses debuggers, we use a general purpose
register to compute the new stack pointer value, and only set the SP
once after all computations are done.
