The Raspberry Pi 3 now allows one to enable JTAG on the Alt4 pins from the config.txt file. This should make it unnecessary to enable it by default in the U-boot build.

See the following Issue: OP-TEE/optee_os#1634

I'm also opening a PR in op-tee/build.

@jogarock thanks for looking into this. I'd be more than happy to get rid of this. But to me it sounds like with your changes, we are more or less reverting this back to vanilla u-boot code? If that is the case, then I think it's even better to update our rpi3.xml files to point to the upstream u-boot instead. We prefer using upstream trees when possible. What do you think?

@jforissier , regardless if we use upstream or decide to merge this, I think this should wait until after the 2.5.0 release.
