uwb: doc: bring uwb documentation up to date

Browse Source 
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.

The main building block here is the UWB device (struct uwb_dev). For
each device that pops up in radio presence (ie: the UWB host receives a
beacon from it) you get a struct uwb_dev that will show up in
/sys/class/uwb and in /sys/bus/uwb/devices.
/sys/bus/uwb/devices.
For each RC that is detected, a new struct uwb_rc is created. In turn, a
RC is also a device, so they also show in /sys/class/uwb and
/sys/bus/uwb/devices, but at the same time, only radio controllers show
up in /sys/class/uwb_rc.

[*] The reason for RCs being also devices is that not only we can
see them while enumerating the system device tree, but also on the
radio (their beacons and stuff), so the handling has to be
likewise to that of a device.
For each RC that is detected, a new struct uwb_rc and struct uwb_dev are
created. An entry is also created in /sys/class/uwb_rc for each RC.
Each RC driver is implemented by a separate driver that plugs into the
interface that the UWB stack provides through a struct uwb_rc_ops. The
