[PATCH v2 00/12] Enable PPS API in RTEMS6

[Gabriel Moyano]

Second version of patches for enabling PPS API in RTEMS6. They have the following improvements:
- Add function _Timecounter_Get_frequency()
- Move hardpps to the _ namespace
- Add a test (sptest/sppps01) for testing basic behaviour of struct pps_state
- Add definition of atomic_load_int() as a relaxed atomic load
- Remove the option for PPS_SYNC and add the #define
