PCI: dwc: Adjust to recent removal of PCI_MSI_IRQ_DOMAIN

PCI: dwc: Adjust to recent removal of PCI_MSI_IRQ_DOMAIN

a474d3fbe287 ("PCI/MSI: Get rid of PCI_MSI_IRQ_DOMAIN") removed
PCI_MSI_IRQ_DOMAIN and changed all references to refer to PCI_MSI instead.

ba6ed462dcf4 ("PCI: dwc: Add Baikal-T1 PCIe controller support")
independently added PCIE_BT1, depending on PCI_MSI_IRQ_DOMAIN.

Both commits appeared in v6.2-rc1, so the latter missed the conversion from
PCI_MSI_IRQ_DOMAIN to PCI_MSI.  Update PCIE_BT1 to depend on PCI_MSI
instead.
