The UWB stack has some sysfs APIs that will change thus it's best
marked as EXPERIMENTAL until these APIs are finalized.

Add a facility for PALs to have symlinks to their radio controller
(and vice-versa) and make WUSB host controllers use this.

The current identification IE doesn't include any useful information
(the vendor ID is from the EUI-48) and it causes problems with certain
hardware/firmware so don't transmit one.

IOGear firmware versions >= 1.4.12224 fail to be downloaded because of a
spurious (and harmless) RCEB received after the download notification. This
patch handles this RCEB and keeps compatibility with future versions that might
not emit this RCEB.
i1480_rceb_check() is reused to check for the RCEB. It is also refactored with
improved comments and reused in another place in mac.c where the checking was
being duplicated.
This patch was tested on both i1480 and GUWA100U HWAs, with all firmware
versions currently available.

Some hardware/firmware combinations (most notably an IOGear HWA using the i1480
firmware) kill the host controller after issuing a GET_MAC_PHY_INFO command.
Removing this check seems harmless otherwise.
The patch fixes the issue where the HC is killed, showing the message:
ehci_hcd 0000:00:1d.7: HC died; cleaning up
After this error, USB comes back only after reloading the ehci_hcd module.

The Intel i1480 HWA uses WHCI commands/events even though reporting itself as
WUSB compliant. This patch fixes this by marking it with the
WUSB_QUIRK_WHCI_CMD_EVT flag, which disables WUSB command/event filtering.

The D-Link DUB-1210 HWA uses commands and events from the WHCI specification,
although reporting itself as WUSB compliant. Therefore, we disable WUSB
command/event filtering for it.
USB_DEVICE_AND_INTERFACE_INFO is used for matching only the RC interface.
