arm64: mops: Handle MOPS exceptions from EL1

Browse source

We will soon be using MOPS instructions in the kernel, so wire up the
exception handler to handle exceptions from EL1 caused by the copy/set
operation being stopped and resumed on a different type of CPU.

Add a helper for advancing the single step state machine, similarly to
what the EL0 exception handler does.
