i2c: mpc: unify obtaining the MPC8533/44 I2C clock prescaler w/ MPC8xxx
Commit 8ce795cb0c6b ("i2c: mpc: assign the correct prescaler from SVR") introduced the common helper function for obtaining the actual clock prescaler value for MPC85xx. However, getting the prescaler for MPC8544 which depends on the SEC frequency ratio on this platform, has been always performed separately based on the corresponding Device Tree configuration. Move special handling of MPC8544 into that common helper. Make it dependent on the SoC version and not on Device Tree compatible node, as is the case with all other SoCs. Handle MPC8533 the same way which is similar to MPC8544 in this regard, according to AN2919 "Determining the I2C Frequency Divider Ratio for SCL".
