USB: Move wusbcore and UWB to staging as it is obsolete

The UWB and wusbcore code is long obsolete, so let us just move the code
out of the real part of the kernel and into the drivers/staging/
location with plans to remove it entirely in a few releases.

- *
- * This driver is the firmware uploader for the Intel Wireless UWB
- * Link 1480 device (both in the USB and PCI incarnations).
- *
- * The process is quite simple: we stop the device, write the firmware
- * to its memory and then restart it. Wait for the device to let us
- * know it is done booting firmware. Ready.
- *
- * We might have to upload before or after a phy firmware (which might
- * be done in two methods, using a normal firmware image or through
- * the MPI port).
- *
- * Because USB and PCI use common methods, we just make ops out of the
- * common operations (read, write, wait_init_done and cmd) and
- * implement them in usb.c and pci.c.
- *
- * The flow is (some parts omitted):
- *
- * i1480_{usb,pci}_probe()	  On enumerate/discovery
- *   i1480_fw_upload()
- *     i1480_pre_fw_upload()
- *       __mac_fw_upload()
- *         fw_hdrs_load()

- *     i1480_mac_fw_upload()
- *       __mac_fw_upload()
- *       i1480->setup(()
- *       i1480->wait_init_done()

- *     i1480_phy_fw_upload()
- *       request_firmware()
- *       i1480_mpi_write()
- *         i1480->cmd()           [i1480_{usb,pci}_cmd()]
- *
- * Once the probe function enumerates the device and uploads the
- * firmware, we just exit with -ENODEV, as we don't really want to
- * attach to the device.

- * When the device is connected or driver is loaded, i1480_usb_probe()
- * is called--this will allocate and initialize the device structure,
- * fill in the pointers to the common functions (read, write,
- * wait_init_done and cmd for HWA command execution) and once that is
- * done, call the common firmware uploading routine. Then clean up and
- * return -ENODEV, as we don't attach to the device.
- *
- * The rest are the basic ops we implement that the fw upload code
- * uses to do its job. All the ops in the common code are i1480->NAME,
- * the functions are i1480_usb_NAME().
