075b0185b6 pinctrl: stm32: make pinctrl use hwspinlock
Protect configuration registers with a hardware spinlock.

If a hwspinlock is defined in the device-tree node used it
to be sure that none of the others processors on the SoC could
change the configuration at the same time.

3d2d115a30 dts: add device tree for STM32MP157C-ED1 board
Add minimal devicetree for STM32MP157C-ED1 board,
with only the devices to allow boot from SDCARD:
- RCC for clock and reset
- UART4 for console
- I2C and PMIC
- DDR
- SDMMC0 for SDCard

Waiting Kernel upstream for alignment.
