[PATCH v2 4/8] firmware: imx: scu-pd: Align imx sc msg structs to 4
From: Leonard Crestez <hidden>

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).
Fixes: c800cd7824bd ("firmware: imx: add SCU power domain driver")
