[PATCH v3]Add STM32F746 MCU pinctrl support

[Alexandre TORGUE]

This series adds STM32F746 pinctrl and GPIO support, relies on the
generic STM32 pinctrl driver.

Changes since v2:

According to Linus remark, use builtin_platform_driver() instead of 
device_initcall() as there are nothing to do in driver init function
(except to register driver).

As soon this patch will be accepted, I will send the same update for 
stm32f429 pinctrl. 

Changes since v1:

Thanks to Paul Gortmaker remarks, remove all modular API as this driver is only
built-in one.

Regards

Alex
