====================
Externel ptp clock support

Externel ptp support is required in a scenario like connecting
a external timing device to the chip for time synchronization.
This series of patches adds support to ptp driver to use external
clock and enables PTP config in CN10K MAC block (RPM). Currently
PTP configuration is left unchanged in FLR handler these patches
addresses the same.
