Subject: soc: imx-scu: Align imx sc msg structs to 4
Git-commit: f10e58a5d20e1cf3a39a842da92c9dd0c3c23849
Patch-mainline: v5.6-rc5
References: jsc#SLE-16106

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).
