pinctrl: imx: scu: Align imx sc msg structs to 4 



commit 4c48e549f39f8ed10cf8a0b6cb96f5eddf0391ce 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).
