Amelie Delaunay 1490d9f841 pinctrl: Add STMFX GPIO expander Pinctrl/GPIO driver 
This patch adds pinctrl/GPIO driver for STMicroelectronics
Multi-Function eXpander (STMFX) GPIO expander.
STMFX is an I2C slave controller, offering up to 24 GPIOs.
The driver relies on generic pin config interface to configure the GPIOs.
