firmware: imx: misc: Align imx sc msg structs to 4
commit5.4-rM2-2.2.x-imx-squashed1e6a4eba69
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: 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.
