u-boot-imx: deploy multiple boot images for i.MX 8M

if env UBOOT_CONFIG contains multiple U-boot configurations,
then "do_deploy_append_mx8m" always returns an error due to
installing the same dtb-file defined in env UBOOT_DTB_NAME.
Even env UBOOT_DTB_NAME contains the same dtb-name for all
U-boot configs it can not be used without an extra suffix
(U-boot config) because different U-boot configs can
generate different dtb files based on the same dts file.

In case different UBOOT_DTB_NAMEs are used in U-boot
configurations, then the same flags for env UBOOT_DTB_NAME
must be used in the machine configuration as in
U-boot configurations.

UBOOT_CONFIG = "a b"
UBOOT_DTB_NAME[a] = "a.dtb"
UBOOT_DTB_NAME[b] = "b.dtb"
