ARM: dts: stm32: set i2c4 bus freq to 400KHz on stm32mp157c-ed1
On this board, the I2C4 bus has only a single slave (pmic) which supports I2C Fast Mode hence setting bus frequency to 400 KHz. Signed-off-by: Alain Volmat <alain.volmat@st.com> Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com>
