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:

Changes in v2:
- Add comment to CAN phy xceiver node
- Fix order of regulator-{max,min}-microvolt properties
