firmware: imx: Align imx_sc_msg_req_cpu_start to 4 



commit f5bfeff44612d304deb100065a9f712309dc2783 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).
