Sheetal Tigadoli 7aae5929cb drivers:nvpps:nvpps: support use of higher PPS freq ...

- support use of higher PPS freq in nvpps. The freq value
is read from primary mac interface's "nvidia,pps_op_ctrl"
field and vetted for valid values(0,1,2,4,5 & 8).
- To use higher PPS freq, nvpps needs to update K_INT and
REF_FREQ.INC value and also increase the freq of monitoring
thread.
