This patch adds a new device STM32L4x5 GPIO device and is part
of a series implementing the STM32L4x5 with a few peripherals.

Changes from RFC v1 :
- `stm32l4x5-gpio-test.c` : correct typos, make the test generic,
add a test for bitwise writing in register ODR
- `stm32l4x5_soc.c` : connect gpios to their clock, use an
array of GpioState
- `stm32l4x5_gpio.c` : correct comments in `update_gpio_idr()`,
correct `get_gpio_pins_to_disconnect()`, correct `stm32l4x5_gpio_init()`
and initialize the clock, add a realize function
- add a summary in the commit messages
- update MAINAINERS
