irqchip/sg2042-msi: Introduce configurable chipinfo for SG2042

As the controller on SG2044 uses different msi_parent_ops and a difffernt
irq_chip, it is necessary to provide that information to the probe function.

Add a new chipinfo structure to hold that information, implement the
necessary logic and make SG2042 use it.
