FROMLIST: irqchip/sg2042-msi: Fix broken affinity setting

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.

Since the PCI template domain supports irq_startup/irq_shutdown, set
irq_chip_[startup/shutdown]_parent for irq_startup/irq_shutdown. So
the irq can be started properly.

Fixes: e96b93a ("irqchip/sg2042-msi: Add the Sophgo SG2044 MSI interrupt controller")
