Add specific init priority for the stm32 DMAMUX device higher than the CONFIG_DMA_INIT_PRIORITY, to be sure that the DMAMUX initialization always comes after the stm32 DMA device init. Its default value is set to 41 when the DMA_INIT_PRIORITY is KERNEL_INIT_PRIORITY_DEFAULT (=40). Signed-off-by: Francois Ramu <francois.ramu@st.com>
