[CPUFREQ] S3C64xx: Notify transition complete as soon as frequency ch…

…anged The CPUFREQ_POSTCHANGE notification is used to update things that depend on the system clock rates. Since this may include the interfaces used to talk to the regulators do the notification before we try to update regulators to reflect lowered system clock rate. The voltage scaling is just a power optimisation and may not happen at all so there's no concern about it not having completed.
