BeagleBoard.org PocketBeagle 2 is an upgraded version of the popular
PocketBeagle. It is based on Texas Instruments AM6232 or AM6254 SoC.
Its dual or quad A53 cores can provide higher performance than classic
PocketBeagle. The new design comes with pre-soldered headers, a 3-pin
JST-SH 1.00mm UART debug port, a USB-C port, Texas Instruments
MSPM0L1105 Cortex-M0+ MCU for ADC, 512MB RAM, and a LiPo Battery charger.
MSPM0L1105 firmware source: https://openbeagle.org/pocketbeagle/mspm0-adc-eeprom
* EEPROM 24c32 emulation
* ADC ad7291 emulation

Changes since v2:
- cleanup unused serial aliases
- cleanup unused sdhci0 (un-populated) aliases
- cleanup unused main_i2c1 (un-populated) aliases
- add missing main_i2c0 aliases
- fix bootph, function, color, gpios order in leds nodes
- drop local cpsw disable, needs to be moved to k3-am62-main
- MSPM0L1105 add firmware source and note where emulated
- usb0 add note about Type-C connector, but only wired for USB 2.0
- usb1 add compatible note with original PocketBeagle expansion boards
Changes since v1:
- fix '_' in main-i2c2-default-pins
- aliases i2c match original pocketbeagle
- add mcu_m4fss with reseved memory and mailbox
- drop unused main_gpio0_pins_default pinmux
- drop unused main_gpio1_pins_default pinmux
- drop unused main_spi2_pins_gpio pinmux
- Reserve 128MiB of global CMA
