modules: hal_ethos_u: Update to latest Ethos-U rev

What is changed?
Added config for Ethos-U85 and, the module `hal_ethos_u` now points
to the latest revision which has support for Arm Ethos-U85 NPU.

Why do we need this change?
This will help in validating the NPU when we add support for FVP
testing for Ethos-U85.
