boot_cpuid and init_thread_info.cpu are redundant, just use the
var that stays around longer and add a define to make boot_cpuid
point at the correct value

boot_cpudid_phys is not needed and can completly go away from the
SMP case, we leave it there for the non-SMP case since the paca
struct is not around to store this info

This patch also has the effect of having the logical cpu number
of the boot cpu be updated correctly independently of the ordering
of the cpu nodes in the device tree.

So what about head_fsl_booke.S comparing boot_cpuid to -1 ? That seems
to be broken now in at least 2 ways, boot_cpuid doesn't exist anymore
and you don't initialize it to -1 either...

This is 4/5 which is also waiting for your review.
