Following changes are necessary to use LP3943 LED driver present
in 96Boards Neonkey board
1. Enable I2C_3 interface
2. Reduce the speed of I2C_3 bus on 96Boards Neonkey. Due to some
design quirks, on board LP3943 LED driver connected to I2C_3
operates only at Standard speed of 100KHz.

Configure SPI using DT for the following STM32 boards:
96b_neonkey
nucleo_f091rc
nucleo_f334r8
nucleo_f401re
nucleo_l432kc
nucleo_l476rg
SPI nodes in <board>.dts file are populated matching boards existing
pinmux default configuration and enabled in Kconfig.defconfig if
SPI is enabled.
For nucleo_l476rg board SPI2 and SPI3 nodes are not yet added, because
of missing pinmux defines.
Fixes#5836

Move the dts files into the board dir so that board ports can be more
standalone. This will allow us at some point to have board ports
outside of the tree.
