config: Warn Beaglebone PRU users that pinmux settings are not updated

Browse Source 
The Beaglebone hardware prevents the PRU from updating the pinmux
board settings.  As a result, the PRU can't directly change the pin
direction or change the pullup resistor settings.  Warn the Beaglebone
users of this limitation.
