From: Philippe Mathieu-Daudé <philmd@linaro.org>

The ARMv7M QDev container accesses the QDev SysTickState
by its secure/non-secure bank index. In order to make
the "hw/intc/armv7m_nvic.h" header target-agnostic in
the next commit, first move the M-profile bank index
definitions to "target/arm/cpu-qom.h".
