[hpsdr] Mercury-EU diversity mode configuration

[Phil Harman]

Hi Berndt,

Whilst that would work there is then no guarantee that the phase of the two 
122.88MHz clocks will be stable with time/temperature.

A better solution is to feed the 122.88MHz clock from one board to the other 
via a short twisted pair using the LVDS transceivers on the Mercury board.
