ice: Add in/out PTP pin delays



HW can have different input/output delays for each of the pins.

Currently, only E82X adapters have delay compensation based on TSPLL
config and E810 adapters have constant 1 ms compensation, both cases
only for output delays and the same one for all pins.

E825 adapters have different delays for SDP and other pins. Those
delays are also based on direction and input delays are different than
output ones. This is the main reason for moving delays to pin
description structure.

Add a field in ice_ptp_pin_desc structure to reflect that. Delay values
are based on approximate calculations of HW delays based on HW spec.

Implement external timestamp (input) delay compensation.

Remove existing definitions and wrappers for periodic output propagation
delays.
