Fixed B2x0 doc, man pages

* usrp_b200.dox: added information on GPIO header
* usrp_b200.dox: added missing footnote on things only on B210
* usrp_b200.dox: added paragraph on bw adjustment
* uhd_usrp_probe.1/uhd_find_devices.1: added type=e3x0 listing

 .SS Identifying by serial number
 
 All USRP devices are given a unique serial number, which can be used to identify a device as follows:

+\subsection b200_fe_bw Frontend bandwidth
+
+The analog frontend has a seamlessly adjustable bandwidth of 200 kHz to 56 MHz.
+
+Generally, when requesting any possible master clock rate, UHD will
+automatically configure the analog filters to avoid any aliasing (RX) or
+out-of-band emissions whilst letting through the cleanest possible signal.
+
+If you, however, happen to have a very strong interferer within half the master
+clock rate of your RX LO frequency, you might want to reduce this analog
+bandwidth.  You can do so by calling
+uhd::usrp::multi_usrp::set_rx_bandwidth(bw).
+
+The property to control the analog RX bandwidth is `bandwidth/value`.
+
+UHD will not allow you to set bandwidths larger than your current master clock
+rate.
