[PATCH v2 01/22] arm64: Make the CPU information more clear

[Suzuki K. Poulose]

At early boot, we print the CPU version/revision. On a heterogeneous
system, we could have different types of CPUs. Print the CPU info for
all active cpus.

Also, remove the redundant 'revision' information which doesn't
make any sense without the 'variant' field.
