Subject: [PATCH] firmware: imx: scu-pd: Align imx sc msg structs to 4
commit 7c1a1c814ccc858633c761951c2546041202b24e 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).
