Sometimes there was an issue that the link didn't came up or the slave halted in state "listening".
This might have been due to the sysclk PLL not yet being in lock after switching to ref_clock.

Set bit for Synchronous Reset R, A and B counters on SYNC_n pin

- updated WB-generated file
- added info about configurable clock domain of streamers data

- hdl software reset
- fixed latency timeout
- fixed latency statistics

This is needed for PPSGen handling cleanup. Now PPSGen is controlled by PPSi.

When testing with newer compilers and newlib, a mismatch surfaced in
the definition of intptr_t, int32_t, uint32_t.  I don't know why the
library header gets picked up.

This patch, though ugly, fixes the problem by using the "ifdef" names
found in lm32-elf/include/sys/_stdint.h (the offending file).
