[PATCH] ARM: dts: imx: Pass an empty 'chosen' node

[Fabio Estevam]

Commit 7f107887d199 ("ARM: dts: imx: Remove skeleton.dtsi") causes boot
issues when the bootloader does not create a 'chosen' node if such node
is not present in the dtb.

The reason for the boot failure is well explained by Javier Martinez
Canillas: "the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info."

, so pass an empty 'chosen' node to fix the boot problem.

This issue has been seen in the kernelci reports with Barebox as
bootloader.
