rules: add ARM Trusted Firmware-A

Trusted Firmware-A (TF-A) is a reference implementation of secure world
software for Arm A-Profile architectures (Armv8-A and Armv7-A).

TF-A is used as first-stage bootloader on the STM32MP1. We'll use
barebox for second-stage only for now, thus add a rule for TF-A.
