configs/imx8mp-evk_defconfig: new defconfig

Browse Source 
Add a new defconfig for the imx8mp-evk board that uses upstream
components, such as:

- Linux Kernel: Upstream version 6.12.16
- U-boot: Upstream version 2025.01
- ATF: Upstream version 2.12

Based on bcc7993283 ("configs/polyhex_debix_model_a_defconfig: new
defconfig") from Gilles Talis.

[Julien:
 - replace linux-headers.hash with a symlink to linux.hash
 - update kernel hash to 6.12.16 to match defconfig version

NXP i.MX8MP EVK
===============
This is a Buildroot target for building an image for the imx8mp-evk
board using upstream components: TF-A, U-Boot and kernel.
How to build it
===============
Configure Buildroot and build it:
$ make imx8mp-evk_defconfig
$ make
Flashing the SD card image
==========================
Copy the sdcard.img file into the SD card:
$ sudo dd if=output/images/sdcard.img of=<your-sd-device>; sync
Booting the board
=================
To boot your newly created system:
- Insert the SD card in the MicroSD slot of the board.
- Connect a serial to USB cable to the DEBUG port.
- Open a terminal on ttyUSB2 port. For example: sudo picocom -b 115200 /dev/ttyUSB2
- Power on the board.
