arm64: Silence gcc warnings about arch ABI drift
Since GCC 9, the compiler warns about evolution of the platform-specific ABI, in particular relating for the marshaling of certain structures involving bitfields. The kernel is a standalone binary, and of course nobody would be so stupid as to expose structs containing bitfields as function arguments in ABI. (Passing a pointer to such a struct, however inadvisable, should be unaffected by this change. perf and various drivers rely on that.) So these warnings do more harm than good: turn them off. We may miss warnings about future ABI drift, but that's too bad. Future ABI breaks of this class will have to be debugged and fixed the traditional way unless the compiler evolves finer-grained diagnostics.
