Instead of using the hard-coded bus speed value I2C_SPEED_STANDARD_RATE,
use the actual configured bus speed. This way the bus speed doesn't
change suddenly after calling the imx_lpi2c_probe_chip() function for
example.

Drop the second parameter of bus_i2c_init(). In bus_i2c_init(), do:
struct dm_i2c_bus *i2c = dev_get_uclass_priv(bus);
int speed = i2c->speed_hz;
That should clean the proliferation of "speed" variable.
