Subject: [PATCH v2 0/2] Add devicetree for NXP i.MX93 FRDM board

I could not test all features of the board, therefore a lot of stuff is
omitted from the devicetree. but this is enough to have the board boot
via eMMC or SD-Card, debug via debug USB connector and have a network
connection.

The FRDM i.MX 93 development board is a low-cost and compact development
board featuring the i.MX93 applications processor.

It features:
- Dual Cortex-A55
- 2 GB LPDDR4X / LPDDR4
- 32 GB eMMC5.1
- MicroSD slot
- GbE RJ45 x 2
- USB2.0 1x Type C, 1x Type A

This file is based upon the one provided by nxp in their own kernel and
yocto meta layer for the device, but adapted for mainline.

Changes in v2:
- 1/2: remove CAN node, as it has not been tested.
- 1/2: ran dt-format (Thanks Frank Li)
	But also reordered some nodes afterwards again to have
	regulator-min before regulator-max, have the pinmux at the end
	of the file, and have the regulator-name as the first node
	inside the regulators.
	Re-added comments, that were deleted.
- 1/2: changes subjet to ar64:dts (Thanks Fabio Estevan)
- 1/2: removed reg_vdd_12v (Tanks Fabio Estevan)
- 1/2: added aliases for rtc, emmc, serial (Thanks Fabio Estevan)
- reordered the series to have documentation before dts. (Thanks
  Krzystof Kozlowski)
