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.

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.
