-STMicroelectronics STM32 CEC driver

-Required properties:
- - compatible : value should be "st,stm32-cec"
- - reg : Physical base address of the IP registers and length of memory
-	 mapped region.
- - clocks : from common clock binding: handle to CEC clocks
- - clock-names : from common clock binding: must be "cec" and "hdmi-cec".
- - interrupts : CEC interrupt number to the CPU.
-
-Example for stm32f746:
-
-cec: cec@40006c00 {
-	compatible = "st,stm32-cec";
-	reg = <0x40006C00 0x400>;
-	interrupts = <94>;
-	clocks = <&rcc 0 STM32F7_APB1_CLOCK(CEC)>, <&rcc 1 CLK_HDMI_CEC>;
-	clock-names = "cec", "hdmi-cec";
-};
