arm64: kvm: Annotate assembly using modern annoations
In an effort to clarify and simplify the annotation of assembly functions in the kernel new macros have been introduced. These replace ENTRY and ENDPROC with separate annotations for standard C callable functions, data and code with different calling conventions. Update the more straightforward annotations in the kvm code to the new macros.
