kernel: add patches for SFP support on NXP Layerscape/DPAA2 (arm64)

These two patches are needed to support SFP's on NXP DPAA2 platforms
(e.g Traverse Ten64).

The deadlock issue patch was submitted upstream a while ago and
rejected, however I am not aware of any better solutions at present.

The 10G mode additions are part of mainline since 5.16.

These two .patches were sourced from our patchset over here:
