[PATCH 2/6] hw/arm/raspi: Fix smpboot[] on big-endian hosts

[Philippe Mathieu-Daudé]

ARM CPUs fetch instructions in little-endian.

smpboot[] encoded instructions are written in little-endian.
This is fine on little-endian host, but on big-endian ones
the smpboot[] array ends swapped. Use the const_le32()
macro so the instructions are always in little-endian in the
smpboot[] array.
