bootstd: Scan all bootdevs in a boot_targets entry
When the boot_targets environment variable is used with the distro-boot
scripts, each device is included individually. For example, if there
are three mmc devices, then we will have something like:
boot_targets="mmc0 mmc1 mmc2"
In contrast, standard boot supports specifying just the uclass, i.e.:
boot_targets="mmc"
The intention is that this should scan all MMC devices, but in fact it
currently only scans the first.
Update the logic to handle this case, without required BOOTSTD_FULL to
be enabled.
I believe at least three people reported this, but I found two.
