[PATCH] powerpc/e5500: Set r5 to point to cpu spec in setup_cpu_e5500()

[Kumar Gala]

From: Laurentiu Tudor <Laurentiu.Tudor at freescale.com>

e500mc and e5500 share some eary setup code that need r5 to point to the
cpu spec structure.  setup_cpu_e500mc() sets it but setup_cpu_e5500()
didn't.

This caused a crash on 32 bit e5500 running under hypervisor, when
__setup_e500mc_ivors() tried to access the cpu features field.
