dts pinctrl definitions were pushed in tree without the code
available to deal with it. They have been kept waiting for the
code, but this is taking much more time than initially thought.
So in current zephyr tree, for all STM32 boards, we have pinmux.c
file which is used to configure pins and these files that are
basically no-op. This situation is creating a lot of confusion
especially to new comers, and create useless maintenance effort.
Remove these files for now.
When zephyr will ready to use them, this commit could be reverted.

Add #pwm-cells to the STM32 PWM binding and dts files. This is to
support have a pwms clients work properly.

To move forward and remove use of Kconfig in dts files lets just create
SoC specific dtsi files that the boards can include. We also seperate
out the F4 dtsi files into their own dir.
