irqchip/sg2042-msi: Fix broken affinity setting
When using NVME on SG2044, the NVME drvier always complains about "I/O tag
XXX (XXX) QID XX timeout, completion polled", which is caused by the broken
affinity setting mechanism of the sg2042-msi driver.
The PLIC driver can only the set the affinity when enabled, but the
sg2042-msi driver invokes the affinity setter in disabled state, which
causes the change to be lost.
Cure this by implementing the irq_startup()/shutdown() callbacks, which
allow to startup (enabled) the underlying PLIC first.
Fixes: e96b93a97c90 ("irqchip/sg2042-msi: Add the Sophgo SG2044 MSI interrupt controller")
