Add UUU_BOOTLOADER_UNTAGGED flag to add the possibility to deploy a
imx-boot binary without the tagged footer
'UUUBURNXXOEUZX7+A-XY5601QQWWZ%sEN' at the end.
The addition of the footer 'UUUBURNXXOEUZX7+A-XY5601QQWWZ%sEN' at the end
causes issues when the binary is loaded into RAM memory, this footer may
cause issues where the binary size exceeds the typical USB package size
used by UUU (1021 bytes).
As example, if the footer is split across two distinct USB packages,
such as sending 'UUUBURNXXXOE' in the last packet and
'UZX7+A-XY5601QQWWZ%sEND' in the next one, it can lead to UUU halting
while waiting for a response in SDPS mode.
After sending 'UUUBURNXXXOE', iMX8MP's boot room starts SPL, not waiting
for the next packet ('UZX7+A-XY5601QQWWZ%sEND'), leading to UUU
breaking.
Therefore, deploy both binaries separately (-tagged and -untagged) to
allow users to choose the appropriate binary.
