fdt: Rename the DEV_TREE_BIN Makefile flag to to EXT_DTB
This seems like a better name. This is a patch-up to the earlier commit
63b4b5b, and also removes a redundant Makefile change.

You cannot use more than one of these options at the same time.
To use a device tree file that you have compiled yourself, pass
-DEV_TREE_BIN=<filename> to 'make', as in:
+EXT_DTB=<filename> to 'make', as in:
- make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb
+ make EXT_DTB=boot/am335x-boneblack-pubkey.dtb
Then U-Boot will copy that file to u-boot.dtb, put it in the .img file
if used, and u-boot-dtb.bin.
