mvebu: Add support for kernel 4.14

Add support for kernel 4.14 to the mvebu target.

This also replaces the old sfp and phylink patches with new versions
from Russell's clearfog-4.13 branch

+
+In others board we have the sata led set to function
+with the sata led trigger by default.
+This patch makes the same for these board that have sata

+
+Nothing guarantees that the thread will run in time, so the
