Philips PNX8550 USB Host driver compile fix

Hello, Ralf, Pete,

The current ohci-hcd driver is a littel defective.
It's unable to use usb-ohci as modules in the case when PCI and on-chip USB are enabled. It just willn't be compiled since there are two calls if module_init in ohci-hcd.

Please look at the patch attached.
I 'm not sure is this patch well for this situation. Any suggestions are very appretiated.

TIA,
Vladimir
