When an STM32 SoC goes into STOP mode, the SPI device is disabled. This cause the pins to not be drived anymore (i.e. they are floating) except through their pull-up or pull-down. From the logical point of view, the NSS pin is held high by a pull-up so it's not a problem if the other pins are floating. However those pins are floating input for the slaves, which increase their power consumption. The solution is to hold the state of the pins through a pull-up or a pull-down. This is already done for the NSS and MOSI pins, but not for SCK. Fix that by using pull-down on the SCK pin the same way it is already done for the MOSI pin. (For the STM32L4 series, this is a regression introduced by the switch to the device tree bindings for SPI pins configuration, see zephyr #24097).
