When using NVME on SG2044, the NVME always complains "I/O tag XXX (XXX) QID XX timeout, completion polled", which is caused by the broken handler of the sg2042-msi driver. As PLIC driver can only setting affinity when enabling, the sg2042-msi does not properly handled affinity setting previously and enable irq in an unexpected executing path. Add irq_startup/irq_shutdown support to the PCI template domain, then set irq_chip_[startup/shutdown]_parent for irq_startup/ irq_shutdown of the sg2042-msi driver. So the irq can be started properly.
