Jiping Ma 5be9ba03ba ice: Additional patches to support the customer use cases
Intel listed total 28 commits that need us to back port. There are
9 commits that are already included in our code base. The commit
"ice: Add support for E825-C TS PLL handling" will not be back
ported since we're not dealing with E825 for 24.09. So we need
back port 18 commits. These commits were introduced in linux-6.9.y
and linux-6.10.y.

To back port these 18 commits successfully, we totally back ported
37 upstream commits.

1) The patches 1-15 are cherry picked to fix the conflicts for patch
   16 ("ice: introduce PTP state machine") and patch 36 "ice:
   Introduce ice_ptp_hw struct". Also will be helpful for the
   subsequent commits back porting.

2) The patches 24-27 are cherry picked to fix the conflicts for patch
   28 ("ice: Fix debugfs with devlink reload")

3) The minor adjust was done for the patches 17, 21, 23 and 33 to
   fit with the context change.

Verification:
- installs from iso succeed on servers with ice(Intel Ethernet
  Controller E810-XXVDA4T Westport Channel) and i40e hw(Intel
  Ethernet Controller X710) for rt and std.
- interfaces are up and pass packets for rt and std.
- create vfs, ensure that they are picked up by the new iavf
  driver and that the interface can come up and pass packets
  on rt and std system.
- Check dmesg to see DDP package is loaded successfully and
  the version is 1.3.36.0 for rt and std.
