Makefile: Drop unnecessary -dtb suffixes

When OF_CONTROL is enabled, u-boot-dtb.* files are the same as u-boot.*
files. So we can use the latter for simplicity.

fdt: Replace u-boot-dtb.bin with u-boot.bin
At present u-boot.bin holds the plain U-Boot binary without the device tree.
This is somewhat annoying since you need either u-boot.bin or u-boot-dtb.bin
depending on whether device tree is used.

This series adjusts the build such that u-boot.bin includes a device tree if
enabled, and the plain binary is in u-boot-nodtb.bin. For now u-boot-dtb.bin
remains the same.

This should be acceptable since:

- without OF_CONTROL, u-boot.bin still does not include a device tree
- with OF_CONTROL, u-boot-dtb.bin does not change

The main impact is to build systems which are set up to use u-boot.bin as
the output file and then add a device tree. These will have to change to use
u-boot-nodtb.bin instead.

The original decision to use a separate u-boot-dtb.bin was aimed at allowing
any device tree file to be concatenated to the u-boot.bin image after the
build. However this no-longer seems so important. More important is the
convenience of using the same output file regardless of the setting for
