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.
