ptp: netc: add external trigger stamp support
The NETC Timer is capable of recording the timestamp on receipt of an
external pulse on a GPIO pin. It supports two such external triggers.
The recorded value is saved in a 16 entry FIFO accessed by
TMR_ETTSa_H/L. An interrupt can be generated when the trigger occurs,
when the FIFO reaches a threshold or overflows.
