soc: imx-scu: Align imx sc msg structs to 4

Browse source 
commit f10e58a5d20e1cf3a39a842da92c9dd0c3c23849 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).
