Subject: [PATCH] tty/serial: tegra: Use engineering names in DT compatible property

Engineering names are more stable than marketing names. Hence, use them
for Device Tree compatible properties instead.

Greg, This builds on patches Grant has (or has said he will have) in his
devicetree/next branch, so I assume this change would be merged through
the same route.

Grant, this patch is physically against devicetree/arm. The of-serial.txt
change should also apply to devicetree/next as is, and you'd previously
indicated that you'd queue the addition of the Tegra entry to of_serial.c
in your devicetree/next branch, so this should apply on top of that once
you have done so. Finally, this should go into devicetree/test too.
