Remove usage of Kconfig symbols I2C_X and rely on overlay
to enable i2c instances in samples for stm32 boards

I2C_STM32_V1 and I2C_STM32_V2 are Kconfig symbols used to
select STM32 I2C driver variant based on I2C IP available on a
given STM32 SoC.
Being SoC dependent, they are automatically selected in soc/
if CONFIG_I2C is set. Then there is no need to define them at board
level, nor for a specific application like this is done in
some sample or test applications. Remove these definitions when
this is the case.

Add sample application for TI LP3943 LED driver. This application
displays a continuous pattern that turns on 16 LEDs at 1s one by
one until it reaches the end and turns off LEDs in reverse order.
