Thomas Huth 34d97308f6 hw/usb/hcd-ohci: Move PCI-related code into a separate file
Some machines (like the pxa2xx-based ARM machines) only have a sysbus
OHCI controller, but no PCI. With the new Kconfig-style build system,
it will soon be possible to create QEMU binaries that only contain
such PCI-less machines. However, the two OHCI controllers, for sysbus
and for PCI, are currently both located in one file, so the PCI code
is still required for linking here. Move the OHCI-PCI device code
into a separate file, so that it is possible to use the sysbus OHCI
device also without the PCI dependency.
