[PATCH v4 7/8] hw/pci-host: Introduce SH_PCI Kconfig entry

[Philippe Mathieu-Daudé]

We want to be able to use the 'SH4' config for architecture
specific features. Add more fine-grained selection by adding
a CONFIG_SH_PCI selector for the SH4 PCI controller.
Move the file with the other PCI host devices in hw/pci-host
and add its missing MAINTAINERS entries.
