boot/uboot: allow to build multiple U-Boot images

Browse Source 
Sometimes it is desired to build multiple U-boot images. E.g. one to
save into flash memory and one for serial load. So far this was not
possible.

This change allows to select any combination of the target formats. They
are all copied to the image folder.

[Thomas:
 - Handle the BR2_TARGET_UBOOT_FORMAT_BIN, which wasn't handled, and
   therefore u-boot.bin was not copied when
   BR2_TARGET_UBOOT_FORMAT_BIN=y.
 - Rename UBOOT_BIN to UBOOT_BINS, since it can now contain multiple
   values.]

Specify the correct name of the output binary created by
U-Boot, if it is not one of the default names. For example:
In case the U-Boot binary for the target platform is not among
the default names, one or more custom names can be listed here.
Use space to separate multiple names.
