[U-Boot] [PATCH] dts/Makefile: Build the user specified dts

[Jagannadha Sutradharudu Teki]

This patch provides a support to build the user specified dts.
If the user is not specifying any dts, then it should build the
dts from CONFIG_DEFAULT_DEVICE_TREE.

$ make -> choose the default dts, defined as CONFIG_DEFAULT_DEVICE_TREE
$ make DEVICE_TREE=<dts-file-name> -> choose the specified dts from the user
