Istvan Csomortani 7cdb11cc34 axi_ad9361: Update the PPS receiver module
+ Add a HDL parameter for the PPS receiver module :
PPS_RECEIVER_ENABLE. By default the module is disabled.
  + Add the CMOS_OR_LVDS_N and PPS_RECEIVER_ENABLE into the CONFIG
register
  + Define a pps_status read only register, which will be asserted, if the free
running counter reach a certain fixed threshold. (2^28) The register can
be deasserted by an incomming PPS only.

Istvan Csomortani c7304922d5 ad_pps_receiver: Initial commit
Add a module to receive 1PPS signal from a GPS module. The module has a
free running counter, which runs on the device's interface clock. The
counter value is latched into a register each time when a 1PPS arrives.
An interrupt signal is also generated in every 1PPS.
