hw/intc: openpic: Correct the reset value of IPIDR for FSL chipset
The reset value of IPIDR should be zero for Freescale chipset, per
the following 2 manuals I checked:
- P2020RM (https://www.nxp.com/webapp/Download?colCode=P2020RM)
- P4080RM (https://www.nxp.com/webapp/Download?colCode=P4080RM)
Currently it is set to 1, which leaves the IPI enabled on core 0
after power-on reset. Such may cause unexpected interrupt to be
delivered to core 0 if the IPI is triggered from core 0 to other
cores later.
Fixes: ffd5e9fe0276 ("openpic: Reset IRQ source private members")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/584
