cpu: make CPU_INTERRUPT_RESET available on all targets

On the x86, some devices need access to the CPU reset pin (INIT#).
Provide a generic service to do this, using one of the internal
cpu_interrupt targets.  Generalize the PPC-specific code for
CPU_INTERRUPT_RESET to other targets.

Since PPC does not support migration across QEMU versions (its
machine types are not versioned yet), I picked the value that
is used on x86, CPU_INTERRUPT_TGT_INT_1.  Consequently, TGT_INT_2
and TGT_INT_3 are shifted down by one while keeping their value.
