Adds a driver for the Si5341 and Si5340 chips. The driver does not fully support all features of these chips, but allows the chip to be used without any support from the "clockbuilder pro" software. If the chip is preprogrammed, that is, you bought one with some defaults burned in, or you programmed the NVM in some way, the driver will just take over the current settings and only change them on demand. Otherwise the input must be a fixed XTAL in its most basic configuration (no predividers, no feedback, etc.). The driver supports dynamic changes of multisynth, output dividers and enabling or powering down outputs and multisynths.
