PCI/MSI: Get rid of PCI_MSI_IRQ_DOMAIN
What a zoo:
PCI_MSI
select GENERIC_MSI_IRQ
PCI_MSI_IRQ_DOMAIN
def_bool y
depends on PCI_MSI
select GENERIC_MSI_IRQ_DOMAIN
Ergo PCI_MSI enables PCI_MSI_IRQ_DOMAIN which in turn selects
GENERIC_MSI_IRQ_DOMAIN. So all the dependencies on PCI_MSI_IRQ_DOMAIN are
just an indirection to PCI_MSI.
Match the reality and just admit that PCI_MSI requires
GENERIC_MSI_IRQ_DOMAIN.
