Update M33 workflow imx95 mkimage

[PetervdPerk-NXP]

Then copy the resulting binary image file, build/mx95evk/m33_image.bin, to the iMX95 directory of the mkimage tool. Build a boot container using mkimage, program it to the boot device, and boot the board. The SM will display a debug monitor prompt on the M33 debug UART.

Is there any more in depth information on how to "program it to the boot device" it's quite basic right now.
I can generate a flash.bin using make SOC=iMX95 flash_lpboot_sm_a55 but to which offset copy it to the sd card to overwrite the existing m33 image.

This should be described in the full documentation. Please build that and look in the Developer's Guide section. It involves using dd to write the image to the card.
