OMAP4+: Correct the dpll lock sequence

The recommended sequence to update the frequencies for
different dplls are core, mpu, iva. Currently though
core dpll is configured first locking is done
only with the emif freq update mechanism. So the sequence
is mpu, core. Change this so that the core dpll is locked
first and only the post dividers are changed by freq update
procedure later.
