The `-t` option to program images with TrustFence didn't make
much sense because the install script is dynamically generated
at build-time with the name of the boot artifacts containing
"signed/encrypted" on their filenames.
This commit:
- Removes `-t` option to simplify the script.
- Determines if programming a signed/encrypted bootloader by
looking at the bootloader filename.
- For NXP platforms, reworks the function that updates the
bootloader to properly program only-signed bootloaders (currently
wrongly using `trustfence update`)
