AM335x's MLO size limit is 109K.
The am33xx.dtsi file adds spare and never used nodes to the dtb.
With this patch we add a file to remove the unused nodes and reduce the
size of the dtb.
Including this file will reduce the lzo packed MLO size about 6K.

v2:
- rename file to am33xx-strip.dtsi
- keep gpio* and uart* nodes
