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).

BUG: KASAN: stack-out-of-bounds in imx_mu_send_data+0x108/0x1f0
It shouldn't cause an issues in normal use because these structs are
always allocated on the stack.
