FTBFS: zephyr-blueprint-gateway-node

I tried to rebuild gateway jasmine

Reproduced instructions from:

https://docs.oniroproject.org/projects/blueprints/en/latest/transparent-gateway.html

Failed this error:

WARNING: zephyr-blueprint-gateway-node-2.6.0+gitAUTOINC+837ab4a915_c3bd2094f9-r0 do_fetch: Failed to fetch URL git://github.com/zephyrproject-rtos/trusted-firmware-m.git;protocol=https;branch=legacy;destsuffix=git/modules/tee/tfm;name=trusted-firmware-m, attempting MIRRORS if available

It looks like this branch has been cleaned up by upstream:

https://github.com/zephyrproject-rtos/trusted-firmware-m/branches

I am trying to see if it can be easily fixed, if not I'll catch up to goofy version of the blueprint.

For the context I was looking if USB debugging was working properly, doorlock does
