[PATCH v1 2/2] pinctrl: stm32: extract and set GPIO offset from devicetree

[Oleksij Rempel <o.rempel@pengutronix.de>]

Update pinctrl-stm32 driver to read gpio_offset from the devicetree
and set it in gpiolib. This enables correct handling of GPIO banks
on stm32mp151aad3, which have non-zero starting indices for some
banks.
