net/mlx5e: Add missing support for PTP_CLK_REQ_PPS request
Add the missing option to enable the PTP_CLK_PPS function.
In this case pin should be configured as 1PPS IN first and
then it will be connected to PPS mechanism.
Events will be reported as PTP_CLOCK_PPSUSR events to relevant sysfs.
Fixes: ee7f12205a
