Prevent i2c_init() in fsl_i2c.c from writing to the data segment before
relocation. Commit d8c82db4 added the ability for i2c_init() to program the
I2C bus speed and save the value in i2c_bus_speed[], which is a global
variable. It is an error to write to the data segment before relocation,
which is what i2c_init() does when it stores the bus speed in i2c_bus_speed[].
