[PATCH v7 10/31] arm: octeontx: Add an empty devicetree file

[Simon Glass]

Add an empty file to prevent build errors when building with
CONFIG_OF_SEPARATE enabled.

Unfortunately there are no build instructions in the U-Boot tree to enable
a real file to be created.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v7:
- Use 'empty' instead of 'fake'
