STM32F4 MCU series is composed of several SOC (STM32F429, STM32F469, ...).
Most of muxing definition are identical. So to avoid to duplicate bindings
definition, this patch create common definitions.

This is a lot of churn. Some confirmation that the resultant dtb is the
same before and after would be nice. Perhaps the script you used to
convert this as well.

I tried to use fdtdump but it seems bugged. So I used directly dtc 
binary to (re)generate dts files (before and after apply the series) and 
I compared "pinmux" field in both case.

Example on stm32f469-disco:

./scripts/dtc/dtc -I dtb -O dts -o stm32f469-disco-after.dts 
stm32f469-disco-after.dtb

./scripts/dtc/dtc -I dtb -O dts -o stm32f469-disco-before.dts 
stm32f469-disco-before.dtb

cat stm32f469-disco-after.dts | grep pinmux
cat stm32f469-disco-before.dts | grep pinmux
