powerpc/fsl_booke: Add support to boot from core other than 0
First we check to see if we are the first core booting up. This
is accomplished by comparing the boot_cpuid with -1, if it is we
assume this is the first core coming up.
Secondly, we need to update the initial thread info structure
to reflect the actual cpu we are running on otherwise
smp_processor_id() and related functions will return the default
initialization value of the struct or 0.
