I2C MUXes described by the i2c-gpio-mux sometimes need a significant amount of time to switch from a bus to another. When a new bus is selected, the first I2C transfer can fail if it occurs too early. There is no way to describe this transition delay that has to be waited before starting the first I2C transfer. Add a 'settle-time-us' property that indicates the delay to be respected before doing the first i2c transfer. Signed-off-by:
