USB: add support for multiple PCI OHCI controllers
Add new configuration variable CONFIG_PCI_OHCI_DEVNO.
In case of several PCI USB controllers on a board this variable
specifys which controller to use.
Also add USB support for sokrates board.
See doc/README.generic_usb_ohci for details.

CONFIG_PCI_OHCI
+If you have several USB PCI controllers, define

+ CONFIG_PCI_OHCI_DEVNO: number of the OHCI device in PCI list
+
+If undefined, the first instance found in PCI space will be used.

PCI Controllers need to do byte swapping on register accesses, so they
should to define:
