arm64: entry: consolidate EL1 exception returns

Browse source

Following the example of ret_to_user, let's consolidate all the EL1
return paths with a ret_to_kernel helper, rather than each entry point
having its own copy of the return code.

There should be no functional change as a result of this patch.
