[PATCH 2/3] ARM: dts: am335x: add support for Moxa UC-2101 open platform

[SZ Lin (æäæ)]

Add support for Moxa UC-2101 open platform

The UC-2101 computing platform is designed for industrial embedded
data acquisition and processing applications.

The features of UC-2101 are:
* eMMC
* SPI flash
* 1x LAN
* 1x RS-232/422/485 ports, software-selectable
* EEPROM
* TPM 2.0
* Watchdog
* RTC
* User gpio-keys
* User LEDs
* User button
