i2c-mpc: add support for the MPC512x processors from Freescale
As I2C interrupts must be enabled for the MPC512x by the setup function as well, "fsl,preserve-clocking" is handled in a slighly different way. Also, the old settings are now reported calling dev_dbg(). For the MPC512x the clock setup function of the MPC52xx can be re-used. Furthermore, the Kconfig help has been updated and corrected.
