feat(stm32mp15-fdts): add Linux Automation GmbH TAC
The Linux Automation Test Automation Controller (LXA TAC)[1] is an embedded software development tool built around the Octavo Systems OSD32MP15x SiP. The device contains an eMMC for storage, a DSA-capable on board ethernet switch with two external ports, dual CAN busses, a power switch to turn a device under test on or off and some other I/O.
