[RobinKastberg]

https://github.com/zephyrproject-rtos/zephyr/blob/2766c788230f54bd30d3b4f1d95af4e87f0c3de8/soc/nxp/imxrt/imxrt11xx/soc.c#L771

Suggested solution: replace with c function with attribute((naked))

[hakehuang]

build command line:

scripts/twister  -p mimxrt1170_evk@B/mimxrt1176/cm7 -T samples/hello_world/ --build-only --force-toolchain --disable-warnings-as-errors

all rt11xx series has such issue.

soc_reset_hook is defined in a global __asm__ statement.
The silent ignore if global __asm__ is IAR known issue TPB-3909.

Support for these kinds of inline global assembly will most probably not be fixed in a timely manner. So this needs to be

1. put in a separate .S-file or
2. put in a attribute((naked)) function.
