90df6a3291 drivers/pinmux: stm32: Use pull-up for _SPI_NSS pins
To work efficiently, SPI_NSS pins require pull-up configuration.
Fix this for whole STM32 series.

Fixes #17998

dca08c95dd stm32: pinmux: spi: Opt for lower power consumption
Fixes #16739. Changed the STM32's SPI MISO/MOSI configurations in order
to reduce the power consumption by approximately 20uA per pin.

According to STM32's Application Notes on GPIO configuration for
low-power consumption, the input pins should be configured with internal
pull-up or pull-down resistor. If a pin is configured as a floating
input, and there is no signal present, the Schmitt trigger randomly
toggles between the logical levels induced by the external noise, thus
increasing the consumption.
