Add support for Moxa UC-8410A open platform

The UC-8410A computing platform is designed
for embedded communication-centric industrial applications

The features of UC-8410A are:
* QSPI flash
* SD slot
* 3x LAN
* 8x RS-232/422/485 ports, software-selectable
* Mini PCIe form factor with PCIe/USB signal
* 2x USB host
* TPM
* Watchdog
* RTC
* User LEDs
* Beeper
