arm: switch real-time clocks to rtc_clock
This lets the user specify the desired semantics. By default, the RTC will follow adjustments from the host's NTP client. "-rtc clock=vm" will improve determinism with both icount and qtest. Finally, the previous behavior is available with "-rtc clock=rt". Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
