Following conversion of stm32 i2c driver to use of DT_NODELABEL macros, configuration of i2c instance in stm32 boards should no more be done thanks to Kconfig symbols, but is done thanks to device tree file. Clean boards files from these symbols. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>
