Erwan Gouriou bddb343b09 stm32: Remove redundant I2C variant Kconfig symbols definitions 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.

PCA9633: 4-Channel RGB
######################

Overview
********

This sample controls 4 LEDs connected to a PCA9633 driver, using the
following pattern:

 1. turn on LEDs
 2. turn off LEDs
 3. set the brightness to 50%
 4. turn off LEDs
 5. blink the LEDs
 6. turn off LEDs

Building and Running
********************

Build the application for the :ref:`stm32373c_eval_board` board, and connect
a PCA9633 LED driver on the bus I2C-1 at the address 0x62.
