I added a reset function for the NVIC/systick as part of the GIC
refactoring work I did recently. These changes should be in QEMU 1.1.

Title:
CortexM, NVIC not reseted if qemu_system_reset_request() called
Status in QEMU:
Fix Released
Bug description:
qemu 0.15.1
Interrupts does not work anymore if system reseted from interrupt.
There is no reset function registered for armv7m_nvic, and as it is
part of the core there is also no any reset for gic/nvic in
cpu_reset() for arm.
possible solution is to add reset function to armv7_nvic.c
static void nvic_reset(void *opaque)
{
nvic_state* s = opaque;
s->systick.control = 0;
s->systick.reload = 0;
s->systick.tick = 0;
qemu_del_timer(s->systick.timer);
gic_reset(&s->gic);
}
and register it in armv7m_nvic_init
