[PATCH v3 2/2] arm64: dts: ti: Add support for the phyCORE-AM67x

[Nathan Morrisson <nmorrisson@phytec.com>]

Add support for the PHYTEC phyCORE-AM67x SoM [1] and the
corresponding phyBOARD-Rigel carrier board [2]. The phyCORE-AM67x SoM
uses the TI AM67x SoC and can come with different sizes and models of
DDR, eMMC, and SPI NOR Flash.

Supported features:
  * Audio playback and recording
  * CAN
  * Debug UART
  * eMMC
  * Ethernet
  * GPIO buttons
  * Heartbeat LED
  * I2C Current sensor
  * I2C EEPROM
  * I2C Light sensor
  * I2C RTC
  * Micro SD card
  * SPI NOR flash
  * USB

Changes in v3:
 * Moved j722s.dtsi include to the carrier board dts, which is
   consistent with how the SoC dtsi is included for other SoM +
   carrier board combinations.
 * Remove pcie for now. We seem to have an issue with the external
   refclk so I will drop the interface.
