i.MX93 IMXUSBLoader compatibility

[Bastian-Krause]

It would be nice to be able to use an i.MX93 in serial download mode with the IMXUSBLoader resource on the LXA TAC.

• [ ] update barebox-tools to >= v2023.12.0 with i.MX93 imx-usb-loader support: https://github.com/barebox/barebox/commit/357dd349cd3aaab2f111d91dc59f8ef614923de2
• [ ] update labgrid to a version recognizing the i.MX93's USB ID: https://github.com/labgrid-project/labgrid/pull/1331 (could be picked to stable)
