uwb: doc: bring uwb documentation up to date
The existing UWB documentation states that UWB devices show up in /sys/class/uwb and /sys/bus/uwb/devices. Up until the most recent changes to add uwb devices to their own bus, neither of these statements were actually true. Now, UWB devices do show up in /sys/bus/uwb/devices so the documentation has been updated to reflect that and removed references to /sys/class/uwb. The existing documentation also states that local UWB radio controller (RC) devices also show up as UWB devices along with their wireless peer UWB devices under /sys/class/uwb. This is not true so that statement has been removed. Signed-off-by: Thomas Pugliese <firstname.lastname@example.org> Signed-off-by: Greg Kroah-Hartman <email@example.com>

The main building block here is the UWB device (struct uwb_dev). For
