Moved the simple_por ngspice simulations into directory ngspice/simple_por/.
Added new directory ngspice/digital_pll/ containing simulation testbenches for
the digital PLL and trimmable ring oscillator.  Added qflow directories for
both;  this was done only to get a valid xspice file for the controller and
a valid SPICE netlist for the ring oscillator.
