[Bug 1876187] [NEW] qemu-system-arm freezes when using SystickTimer on netduinoplus2

[René Sandbote]

Public bug reported:

git commit 27c94566379069fb8930bb1433dcffbf7df3203d

The global variable system_clock_scale used in hw/timer/armv7m_systick.c
is never set on the netduinoplus2 platform, it stays initialized as
zero. Using the timer with the clock source as cpu clock leads to an
infinit loop because systick_timer->tick always stays the same.

To reproduce use to CMSIS function SysTick_Config(uint32_t ticks) to
setup the timer.
