This series updates the Corstone-1000 Cortex-A320 flow to match the current
upstream direction and the in-tree Ethos-U integration model.

It reworks the U-Boot device tree patch layout to separate common and
Cortex-A320-specific changes, adds linux-yocto 6.19 support, aligns the
Ethos-U85 device tree and kernel configuration with the in-tree ethosu
driver, removes the remaining meta-ethos and meta-sca dependency from the
A320 flow, and refreshes the documentation.

The main changes are:
- rework the Corstone-1000 U-Boot CONFIG_OF_UPSTREAM patch layout
- add and prefer linux-yocto 6.19 for Corstone-1000
- update Ethos-U85 DT and kernel config for the in-tree ethosu driver
- drop meta-ethos and meta-sca from the A320 flow
- refresh the user guide for SMP, test_teflon, and the patch-based workaround
