But this method meet issue when do the system PM stress test. IC can't fix it easily. So in the new imx93 A1 chip, IC drop this method, and involve back the old way，use the GPR method to trigger the Flex-CAN stop mode signal. Now NXP claim to drop imx93 A0, and only support imx93 A1. So here add the stop mode through GPR. This patch also fix a typo for aonmix_ns_gpr.
