From: Leonard Crestez <leonard.crestez@nxp.com>
commit 8400ab8896324641243b57fc49b448023c07409a upstream.
The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs.
This produces many oopses with CONFIG_KASAN=y.
Fix by marking with __aligned(4).
