Move USB network drivers to drivers/net/usb.

It is preferable to group drivers by usage (net, scsi, ATA, ...) than
by bus.  When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer
is probably less qualified on networking issues than a networking
maintainer.  Also, from a practical standpoint, chips often
appear on multiple buses, which is why we do not put drivers into
drivers/pci/net.

- * GeneSys GL620USB-A (www.genesyslogic.com.tw)
- *
- * ... should partially interop with the Win32 driver for this hardware.
- * The GeneSys docs imply there's some NDIS issue motivating this framing.
- *
- * Some info from GeneSys:
- *  - GL620USB-A is full duplex; GL620USB is only half duplex for bulk.
- *    (Some cables, like the BAFO-100c, use the half duplex version.)
- *  - For the full duplex model, the low bit of the version code says
- *    which side is which ("left/right").
- *  - For the half duplex type, a control/interrupt handshake settles
- *    the transfer direction.  (That's disabled here, partially coded.)
- *    A control URB would block until other side writes an interrupt.
- *
- * Original code from Jiun-Jie Huang <huangjj@genesyslogic.com.tw>
- * and merged into "usbnet" by Stanislav Brabec <utx@penguin.cz>.
