[PATCH v2 2/2] arm64: dts: freescale: Add phyBOARD-Segin-i.MX91 support

[Primoz Fiser]

Add initial support for the PHYTEC phyBOARD-Segin-i.MX91 board [1] based
on the PHYTEC phyCORE-i.MX91 SoM (System-on-Module) [2].

Supported features:
* Audio
* CAN
* eMMC
* Ethernet
* I2C
* RTC
* SD-Card
* UART
* USB

For more details see the product pages for the development board and the
SoM:
