msm: cpufreq: Initialize cpufreq driver early at boot

MSM cpufreq driver registering with the CPUFreq framework during
late_initcall() may cause the device to be available a few seconds after
the clock driver is ready for changing frequency. This could be bad for
boot and/or thermal performance, since the cpu will continue to boot at
whatever frequency the bootloaders set it to.

Initialize cpufreq driver as part of device_initcalL() but only after
all the clock drivers have had a chance to initialize their devices.
