Add support for external synchronization clock via GPIOs. 1PPS signals are handled via the dedicated 3 GPIOs: SDP3_2, SDP3_3 and GPIO_4. Previously it was not possible to use the external PTP synchronization clock. All possible HW configurations are supported. SDP3_2, SDP3_3, GPIO_4 off, off, off off, in_A, off off, out_A, off off, in_B, off off, out_B, off in_A, off, off in_A, in_B, off in_A, out_B, off out_A, off, off out_A, in_B, off in_B, off, off in_B, in_A, off in_B, out_A, off out_B, off, off out_B, in_A, off off, off, in_A off, out_A, in_A off, in_B, in_A off, out_B, in_A out_A, off, in_A out_A, in_B, in_A in_B, off, in_A in_B, out_A, in_A out_B, off, in_A off, off, out_A off, in_A, out_A off, in_B, out_A off, out_B, out_A in_A, off, out_A in_A, in_B, out_A in_A, out_B, out_A in_B, off, out_A in_B, in_A, out_A out_B, off, out_A out_B, in_A, out_A off, off, in_B off, in_A, in_B off, out_A, in_B off, out_B, in_B in_A, off, in_B in_A, out_B, in_B out_A, off, in_B out_B, off, in_B out_B, in_A, in_B off, off, out_B off, in_A, out_B off, out_A, out_B off, in_B, out_B in_A, off, out_B in_A, in_B, out_B out_A, off, out_B out_A, in_B, out_B in_B, off, out_B in_B, in_A, out_B in_B, out_A, out_B Tested with oscilloscope, 1PPS generator and ts2phc.
