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:
