Subject: [PATCH] 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).
Fixes: d90bf296ae18 ("firmware: imx: Add support to start/stop a CPU")
