This Linaro release updates just the binaries:

Linaro binaries upgraded 16.12 --> 17.01

The toolchain remains at 5.3-2015.05 (gcc 5.3) for both AArch64
and AArch32.

The ARM TF codebase has been tested against these new binaries. This patch
updates the User Guide to reflect that the 17.01 release is now a supported
Linaro Release.
