[PATCH for-5.1? 3/3] msf2-soc, stellaris: Don't wire up SYSRESETREQ

[Peter Maydell <peter.maydell@linaro.org>]

The MSF2 SoC model and the Stellaris board code both wire
SYSRESETREQ up to a function that just invokes
    qemu_system_reset_request(SHUTDOWN_CAUSE_GUEST_RESET);
This is now the default action that the NVIC does if the line is
not connected, so we can delete the handling code.
