i2c: mpc: get MPC8xxx I2C clock prescaler before using it in calculations Obtaining the actual I2C clock prescaler value in mpc_i2c_setup_8xxx() only happens when the clock parameter is set to something other than MPC_I2C_CLOCK_LEGACY. When the clock parameter is exactly MPC_I2C_CLOCK_LEGACY, the prescaler parameter is used in arithmetic division as provided by the caller, resulting in a division by zero for the majority of processors supported by the module. Avoid division by zero by obtaining the actual I2C clock prescaler in mpc_i2c_setup_8xxx() unconditionally regardless of the passed clock value.
