irqchip/loongson-eiointc: Fix irq affinity setting during resume

The hierarchy of PCH PIC, PCH PCI MSI and EIONTC is as following:

        PCH PIC ------->|
                        |---->EIOINTC
        PCH PCI MSI --->|

so the irq_data list of irq_desc for IRQs on PCH PIC and PCH PCI MSI
is like this:

irq_desc->irq_data(domain: PCH PIC)->parent_data(domain: EIOINTC)
irq_desc->irq_data(domain: PCH PCI MSI)->parent_data(domain: EIOINTC)

In eiointc_resume(), the irq_data passed into eiointc_set_irq_affinity()
should be matched to EIOINTC domain instead of PCH PIC or PCH PCI MSI
domain, so fix it.
