ice: add phase offset monitor for all PPS dpll inputs
Implement a new admin command and helper function to handle and obtain
CGU measurements for input pins.
Add new callback operations to control the dpll device-level feature
"phase offset monitor," allowing it to be enabled or disabled. If the
feature is enabled, provide users with measured phase offsets and
notifications.
Initialize PPS DPLL with new callback operations if the feature is
supported by the firmware.
