Benjamin Herrenschmidt 9961d70dfb Improve PLL/MMCM clocks configuration 
We can now pass both the input clock and target clock frequency
via generics. Add support for both 50Mhz and 100Mhz target freqs
for both cases.

Anton Blanchard 03fd06deaf Rework SOC reset 
The old reset code was overly complicated and never worked properly.
Replace it with a simpler sequence that uses a couple of shift registers
to assert resets:

- Wait a number of external clock cycles before removing reset from
  the PLL.

- After the PLL locks and the external reset button isn't pressed,
  wait a number of PLL clock cycles before removing reset from the SOC.
