usrp-e100: bring up the clock as the first thing

We init the clock as the app wants it as the first thing we do.
This greatly simplifies logic, no need to conditionally init.

Clock config: perform soft reset, and removed ignore sync work

Added open/close to iface so we can open and close w/o re-making.

Other misc tweaks involving prints, etc...
