[PATCH v2 7/8] rtc: imx-sc: Align imx sc msg structs to 4

[Leonard Crestez <leonard.crestez@xxxxxxx>]

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).
