ARM: dts: stm32: change pinctrl bindings definition 

Initially each pin was declared in "include/dt-bindings/stm32<SOC>-pinfunc.h"
and each definition contained SOC names (ex: STM32F429_PA9_FUNC_USART1_TX).
Since this approach was approved, the number of supported MCU has
increased (STM32F429/STM32F469/STM32f746/STM32H743). To avoid to add a new
file in "include/dt-bindings" each time a new STM32 SOC arrives I propose
a new approach which consist to use a macro to define pin muxing in device
tree. All STM32 will use the common macro to define pinmux. Furthermore, it
will make STM32 maintenance and integration of new SOC easier .

* 16 : Alternate Function 15
* 17 : Analog
To simplify the usage, macro is available to generate "pinmux" field.
This macro is available here:
- include/dt-bindings/pinctrl/stm32-pinfunc.h
Some examples of using macro:
/* GPIO A9 set as alernate function 2 */
... {
pinmux = <STM32_PINMUX('A', 9, AF2)>;
};
/* GPIO A9 set as GPIO */
... {
pinmux = <STM32_PINMUX('A', 9, GPIO)>;
};
/* GPIO A9 set as analog */
... {
pinmux = <STM32_PINMUX('A', 9, ANALOG)>;
};
Optional properties:
- GENERIC_PINCONFIG: is the generic pinconfig options to use.
Available options are:
