clk: imx: Align imx sc clock msg structs to 4

Browse source 
commit a0ae04a25650fd51b7106e742d27333e502173c6 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).
