[PATCH 25/33] hw/arm/fsl-imx6ul: Let the A7MPcore create/wire the CPU co


From: Philippe Mathieu-Daudé
Subject: [PATCH 25/33] hw/arm/fsl-imx6ul: Let the A7MPcore create/wire the CPU cores
Date: Tue, 12 Dec 2023 17:29:25 +0100

Set the properties on the a7mpcore object to let it create and
wire the CPU cores. Remove the redundant code.
