ppc64/purgatory: Device tree values should be read/stored in Big Endian
The purgatory code reads the device tree's version and stores if needed the
currently running CPU number. These 2 values are stored in Big Endian
format in the device tree and should be byte swapped when running in Little
Endian mode.
Without this fix, when running in SMP environment, kexec or kdump kernel may
fail booting with the following message :
Failed to identify boot CPU
