[PATCH v3 0/3] Add device STM32L4x5 SYSCFG

[Inès Varhol]

Changes from v2 to v3:
- updating the B-L475E-IOT01A machine's documentation file
- using `GPIO_NUM_PINS` instead of 16 in `stm32l4x5_syscfg_init`
- correcting the formatting of multiline indents
- renaming a trace function (`trace_stm32l4x5_syscfg_forward_exti`
instead of `trace_stm32l4x5_syscfg_pulse_exti`)

Changes from v1 to v2:
- explain in 3rd commit why SYSCFG input GPIOs aren't connected and add
a TODO comment in stm32l4x5_soc.c
- use macros `NUM_GPIOS` and `GPIO_NUM_PINS` in
`stm32l4x5_syscfg_set_irq`
- rename STM32L4XX to STM32L4X5, Stm32l4xx to Stm32l4x5
(the SYSCFG implementation is only valid for STM32L4x5 and STM32L4x6
but not for STM32L41xx/42xx/43xx/44xx)
- refactor `STM32L4x5SyscfgState` to `Stm32l4x5SyscfgState` to be
consistent with other peripherals
