This reverts a previous change that was a workaround for tuning glitches
in sweep mode. Increase of TVCO is a better solution.

Previously we zeroed all RFFC5072 frequency synthesizer control
registers, resulting in an invalid configuration which could adversely
affect start-up if the part is enabled before a valid frequency is set.

Fix clock generator initialisation on rad1o.
...
On the CCC 2015 rad1o badge, the Si5351C clock generator is powered
by the RF section supply (named VDD on the schematic).
So clock_gen_init() must be called after enable_rf_power().
Since the Si5351C is off when the RF power is off, there should be
no need for the shutdown/init calls at startup.

The 100 Hz setting that is recommended by the data sheet doesn't seem to
work correctly. The other settings would be appropriate only with the
extended precision RX gateware.
The 600 kHz setting seems like it should be useful with higher sample
rates, but it increases LPF roll-off.
