While the exynos driver does not always need MSI, the generic
deisgnware host code it uses fails to build without it:
WARNING: unmet direct dependencies detected for PCIE_DW_HOST
Depends on [n]: PCI [=y] && PCI_MSI_IRQ_DOMAIN [=n]

^
Add back the dependency that all other designware controllers have.
