[hpsdr] Diversity reception w/dual Merc boards

[Georg Prinz]

Hello Joe,

going through the mails another question came up concerning the
synchronization of two mercury boards:

Does your solution mean that not only the two ADs are synchronized, but
also the following decimation routines on both FPGAs?
