[LinuxPPS] 24 Nov 14:31 - PPS: low level IRQ timestamps recording.

[linuxpps: Rodolfo Giometti <>]

PPS: low level IRQ timestamps recording.  
  
Add low level IRQ timestamps recording for x86 (32 and 64 bits)  
platforms and enable UART clients in order to use it.  
  
This improves PPS precision. :)
