Early exits from for_each_available_child_of_node() should decrement the
node reference counter. Reported by Coccinelle:
drivers/thermal/imx_sc_thermal.c:93:1-33: WARNING:
Function "for_each_available_child_of_node" should have of_node_put() before return around line 97.

i.MX8 SoCs DTS file needs system control macro definitions, so move them
into dt-binding headfile, then include/linux/firmware/imx/types.h can be
removed and those drivers using it should be changed accordingly.

The temperature value passed from SCU could be negative value,
the data type should be signed instead of unsigned.

The i.MX SCU API strongly assumes that messages are composed out
of 4-bytes words but some of our message structs have odd sizeofs,
use __packed __aligned(4) to avoid potential oopses.

i.MX8QXP is an ARMv8 SoC which has a Cortex-M4 system controller
inside, the system controller is in charge of controlling power,
clock and thermal sensors etc..
This patch adds i.MX system controller thermal driver support,
Linux kernel has to communicate with system controller via MU
(message unit) IPC to get each thermal sensor's temperature,
it supports multiple sensors which are passed from device tree,
please see the binding doc for details.
