[PATCH 2/2] arm64: dts: freescale: Add PHYTEC phyBOARD-Nash-i.MX93 support

[Primoz Fiser <primoz.fiser@norik.com>]

Add initial support for PHYTEC phyBOARD-Nash-i.MX93 board [1] based on
the PHYTEC phyCORE-i.MX93 SoM (System-on-Module) [2].

Supported board features:
 * ADC
 * CAN
 * Ethernet 2x
 * EEPROM
 * eMMC
 * Heartbeat LED
 * RTC
 * RS-232/RS-485
 * SD-card
 * TPM 2.0
 * USB

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