Sebastien Bourdeauducq 0c32d07e8b ad9154: new sysref scan 
Print margins around the pre-defined fixed phase.
Also report error if margins are too small.

The fixed phase is also changed by this commit (the value 88 is
from before the new HMC7043 initialization code, and is probably wrong).

Sayma HMC830: update interface and register writes. (#1068) 
* Break the HMC830 init into separate functions for general purpose (but, integer-N) init, setting dividers and checking lock

* Use 1.6mA ICP (which the loop filter was optimized for)

* Go through the data sheet carefully and set all registers to the correct value (e.g. ensure that all settings are correctly optimized for integer-N usage)

* Change divider values (now using 100MHz PFD, which should give lower noise in theory)
