From: Sergey Temerkhanov sergey.temerkhanov@intel.com
[ Upstream commit 97ed20a01f5b96e8738b53f56ae84b06953a2853 ]
Add ice_get_ctrl_ptp() wrapper to simplify the PTP support code in the functions that do not use ctrl_pf directly. Add the control PF pointer to struct ice_adapter Rearrange fields in struct ice_adapter
