AM64 has a single lane SERDES which can be configured to be used
with either PCIe or USB. Define the possilbe values for the SERDES
function in AM64 SoC here.

In case you end up keeping these defines, despite the comment by Rob...

Nitpick, the J721E and J7200 sections have a blank line here, between the
header comment and the actual defines. But mehh...
